the copolymers of the invention have a well - defined structure , having a methacrylic polymeric backbone which has been chemically modified by the addition of a small weight percentage of polysiloxane grafts . when such copolymers are coated on an exposed area of an animal body or on animal hair , non - tacky coatings or localized applications can be aesthetically and comfortably made on those bodies . once applied to a surface , the composition can maintain the presence of active ingredients applied in the composition . the surface characteristics of the copolymeric adhesive composition can be chemically tailored through variation of both the molecular weight of the grafted siloxane polymeric moiety and the total siloxane content ( weight percentage ) of the copolymer , with higher siloxane content and / or molecular weight providing lower initial adhesion . the chemical nature and the molecular weight of the methacrylic polymeric backbone of the copolymer can also be chosen such that the level of adhesion to the substrate can be matched to the requirements of a particular application . since their siloxane content is relatively low , the copolymers of this invention are readily compatible with siloxane - free polymers , for example polymers of composition similar to that of the vinyl or methacrylic backbone . the preferred method of preparation of the compositions of this invention provides graft copolymer of high purity which can be coated directly from the polymerization solvent , if necessary or desired . the resultant coatings do not require curing or crosslinking . however , if enhancement of either shear strength or resistance to solvents or photochemical or oxidative forces is desired , crosslinking may be effected by standard methods well - known in the art , such as radiation curing ( electron beam oir ultraviolet light ) or chemical crosslinking . the siloxane polymeric moieties can be grafted by polymerizing monomer onto reactive sites located on the backbone by attacking preformed polymeric moieties to sites on the backbone , or , preferably , by copolymerizing the methacrylic monomer ( s ), a , and , polar monomer ( s ), b , with preformed polymeric siloxane monomer , c . since the polymeric siloxane surface modifier is chemically bound , it is possible to chemically tailor the compositions of this invention such that a specific degree of cohesiveness and solubility are provided and can be reproduced with consistency . as previously mentioned , the composition of this invention comprises a methacrylate copolymer which is inherently non - tacky at room temperature ( 20 ° c .) and moderate pressure ( 0 . 5 kg / cm 2 ). monovalent siloxane polymeric moieties having a number average molecular weight above about 500 are grafted to the copolymer backbone . the copolymer preferably consists essentially of copolymerized repeating units from a , b , and c monomers and , optionally , b monomers according to the description given above . the a monomer or monomers ( there may be more than one ) are chosen such that a non - tacky material is obtained upon polymerization of a ( or a and b ). representative examples of a monomers are the lower to intermediate methacrylic acid esters of alcohols such as methanol , ethanol , 1 - propanol , 2 - propanol , 1 - butanol , 1 , 1 - dimethyl ethanol , 2 - methyl - 1 - propanol , 1 - pentanol , 2 - pentanol , 3 - pentanol , 2 - methyl - 1 - butanol , 3 - methyl - 1 - butanol , 2 - hexanol , 2 - methyl - 1 - pentanol , 3 - methyl - 1 - pentanol , cyclohexanol , 2 - ethyl - 1 - butanol , 3 - heptanol , benzyl alcohol , 2 - octanol , 6 - methyl - 1 - heptanol , 2 - ethyl - 1 - hexanol , 3 , 5 - dimethyl - 1 - hexanol , 3 , 5 , 5 - trimethyl - 1 - hexanol , 1 - decanol , and 1 - dodecanol , and the like , the alcohols having from 1 to 12 carbon atoms , preferably 1 to 8 carbon atoms , with the average number of carbon atoms being about 4 - 12 . preferably non - tertiary alcohols are used . some small amount of copolymerizable styrene , vinyl esters , vinyl chloride , vinylidene chloride , acryloyl monomers and the like may be used . these comonomers must not prevent the maintenance of a tg of at least 20 . 0 ° c . in the final polymeric composition preferably 30 . 0 ° c ., and more preferably at least 40 . 0 ° c . such monomers are known in the art , and many are commercially available . preferred polymerized a monomer backbone compositions include poly ( isooctyl methacrylate ), poly ( isononyl methacrylate ), poly ( 2 - ethylhexyl methacrylate ), polyisopentylmethacrylate , poly ( n - butyl methacrylate ), poly ( isobutyl methacrylate ), poly ( methylmethacrylate ), and copolymers thereof with other a monomer or monomers . some amount of acrylate may also be present , but only in such amounts that these compositions are not pressure sensitive . according to the practice of the present invention , the b monomers are defined as polar monomers which are different from and copolymerizable with the a monomers . said b monomers must have substituents other than their polymerizable groups ( acryloyl , methacryloyl , vinyl , etc .) and those substituents are selected from the group consisting of amido , nitrile and carboxylic acid groups . representative examples of polar monomer , b , acrylic acid , methacrylic acid , itaconic acid , acrylamide , methacrylamide , n , n - dimethylacrylamide , acrylonitrile , methacrylonitrile , and n - vinyl pyrrolidone . in addition , polymeric monomers or macromonomers ( as will be described hereinafter ) having a t g or t m above about 20 . 0 ° c . are also useful as monomers . representative examples of such polymeric monomers are poly ( styrene ), poly ( α - methylstyrene ), poly ( vinyl toluene ), and poly ( methyl methacrylate ) macromonomers . preferred b monomers are acrylic acid , n , n - dimethylacrylamide , methacrylic acid , and n - vinyl pyrrolidone . the amount by weight of b monomer preferably does not exceed about 30 % of the total weight of all monomers such that excessive firmness of the polymer is avoided . incorporation of b monomer to the extent of about 2 % to about 25 % by weight is most preferred and provides compositions of high cohesive or internal strength , good adhesion to polar surfaces and which also retains good physical properties . the preferred c monomer may be further defined as having an x group which has the general formula ## str1 ## wherein r 1 is a hydrogen atom or a cooh group and r 2 is a hydrogen atom , a methyl group , or a ch 2 cooh group . the z group of the c monomer has the general formula ## str2 ## where r 3 and r 5 are independently lower alkyl , aryl , or fluoroalkyl , where lower alkyl and fluoroalkyl both refer to alkyl groups having from one to three carbon atoms and where aryl refers to phenyl or substituted phenyl ( of up to 20 carbon atoms ). r 4 may be alkyl ( of 1 to 20 carbon atoms ), alkoxy ( of 1 to 20 carbon atoms ), alkylamino ( of 1 to 20 carbon atoms ), aryl ( of up to 20 carbon atoms ), hydroxyl , or fluoroalkyl ( of 1 to 20 carbon atoms ), and r is an integer from about 5 to about 700 . preferably , the c monomer has a general formula selected from the group consisting of the following , where m is 1 , 2 , or 3 , p is zero or 1 , r &# 34 ; may be alkyl ( of 1 to 10 carbon atoms ) or hydrogen , q is an integer from 2 to 6 , s is an integer from zero to 2 , and x , r , and z are as defined above : ## str3 ## the topical composition of this invention is provided by copolymerizing the a , b and c , and , preferably , b monomers followed , when necessary or desirable , by blending with a compatible cosmetic or medicinally active ingredient in order to optimize the ultimate utile properties of the composition . when the above described composition is coated on skin or hair in proper proportions in a composition , no tackiness is observed when the composition is dry . copolymers containing c monomer having a molecular weight less than about 500 are not very effective in providing substantivity , or persistant retention on the skin . copolymers containing c monomer having a molecular weight greater than 50 , 000 effectively provide substantivity , but , at such high molecular weights , possible incompatibility of the c monomer with the remaining monomer during the copolymerization process may result in reduced incorporation of c . a molecular weight of c monomer ranging from about 500 to about 50 , 000 is therefore preferred . a molecular weight range from about 5 , 000 to about 25 , 000 is most preferred . the c monomer is preferably incorporated in the copolymer in the amount of about 0 . 01 to about 50 % of the total monomer weight to obtain the desired properties . the amount of c monomer included may vary depending upon the particular application , but incorporation of such percentages of c monomer having a molecular weight in the above - specified range has been found to proceed smoothly and to result in material which provides effective substantivity for a variety of applications while still being cost effective . the total weight of b and c monomers is preferably within the range of about 0 . 01 to about 70 % of the total weight of all monomers in the copolymer . the c monomers of this invention are terminally functional polymers having a single functional group ( the vinyl , ethylenically unsaturated , acryloyl , or methacryloyl group ) and are sometimes termed macromonomers or &# 34 ; macromers &# 34 ;. such monomers are known and may be prepared by the method disclosed by milkovich et al ., as described in u . s . pat . nos . 3 , 786 , 116 and 3 , 842 , 059 . the preparation of polydimethylsiloxane macromonomer and subsequent copolymerization with vinyl monomer have been described in several papers by y . yamashita et al ., [ polymer j . 14 , 913 ( 1982 ); acs polymer preprints 25 ( 1 ), 245 ( 1984 ); makromol . chem . 185 , 9 ( 1984 )]. this method of macromonomer preparation involves the anionic polymerization of hexamethylcyclotrisiloxane monomer ( d 3 ) to form living polymer of controlled molecular weight , and termination is achieved via chlorosilane compounds containing a polymerizable vinyl group . free radical copolymerization of the monofunctional siloxane macromonomer with vinyl monomer or monomers provides siloxane - grafted copolymer of well - defined structure , i . e ., controlled length and number of grafted siloxane branches . suitable monomers for use in the above - mentioned anionic polymerization are , in general , diorganocyclosiloxanes of the formula ## str4 ## where r 3 and r 5 are as previously defined and where r is an integer of 3 to 7 . preferred are the cyclic siloxanes where r is 3 or 4 and r 3 and r 5 are both methyl , these cyclic siloxanes being hereafter designated d 3 and d 4 , respectively . d 3 , which is a strained ring structure , is especially preferred . initiators of the anionic polymerization are chosen such that monofunctional living polymer is produced . suitable initiators include alkali metal hydrocarbons such as alkyl or aryl lithium , sodium , or potassium compounds containing up to 20 carbon atoms in the alkyl or aryl radical or more , preferably up to 8 carbon atoms . examples of such compounds are ethylsodium , propylsodium , phenylsodium , butylpotassium , octylpotassium , methyllithium , ethyllithium , n - butyllithium , sec - butyllithium , tert - butyllithium , phenyllithium , and 2 - ethylhexyllithium . lithium compounds are preferred as initiators . also suitable as initiators are alkali metal alkoxides , hydroxides , and amides , as well as triorganosilanolates of the formula ## str5 ## where m is alkali metal , tetraalkylammonium , or tetraalkylphosphonium cation and where r 3 , r 4 , and r 5 are as previously defined . the preferred triorganosilanolate initiator is lithium trimethylsilanolate ( ltms ). in general , the preferred use of both strained cyclic monomer and lithium initiator reduces the likelihood of redistribution reactions and thereby provides siloxane macromonomer of narrow molecular weight distribution which is reasonably free of unwanted cyclic oligomers . molecular weight is determined by the initiator / cyclic monomer ratio , and thus the amount of initiator may vary from about 0 . 004 to about 0 . 4 mole of organometallic initiator per mole of monomer . preferably , the amount will be from about 0 . 008 to about 0 . 04 mole of initiator per mole of monomer . for the initiation of the anionic polymerization , an inert , preferably polar organic solvent can be utilized . anionic polymerization propagation with lithium counterion requires either a strong polar solvent such as tertrahydrofuran , dimethyl sulfoxide , or hexamethylphosphorous triamide , or a mixture of such polar solvent with nonpolar aliphatic , cycloaliphatic , or aromatic hydrocarbon solvent such as hexane , heptane , octane , cyclohexane , or toluene . the polar solvent serves to &# 34 ; activate &# 34 ; the silanolate ion , making propagation possible . generally , the polymerization can be carried out at a temperature ranging from about - 50 ° c . to about 100 ° c ., preferably from about - 20 ° c . to about 30 ° c . anhydrous conditions and an inert atmosphere such as nitrogen , helium , or argon are required . termination of the anionic polymerization is , in general , achieved via direct reaction of the living polymeric anion with halogen - containing termination agents , i . e ., functionalized chlorosilanes , to produce vinyl - terminated polymeric monomers . such terminating agents may be represented by the general formula x ( y ) n si ( r ) 3 -- m cl m , where m is 1 , 2 , or 3 and where x , y , n , and r have been previously defined . a preferred terminating agent is methacryloxypropyldimethylchlorosilane . the termination reaction is carried out by adding a slight molar excess of the terminating agent ( relative to the amount of initiator ) to the living polymer at the polymerization temperature . according to the aforementioned papers by y . yamashita et al ., the reaction mixture may be ultrasonically irradiated after addition of the terminating agent in order to enhance functionality of the macromonomer . purification of the macromonomer can be effected by addition of methanol . the copolymerization of the a monomer , b monomer and c monomer is carried out by conventional free radical polymerization such as described by ulrich , u . s . reissue pat . no . 24 , 906 . the monomers are dissolved in an inert organic solvent and polymerized utilizing a suitable free radical initiator which can be either thermally or photochemically activated . suitable thermally activated initiators include azo compounds such as 2 . 2 &# 39 ;- azobis ( isobutyronitrile ), hydroperoxides such as tert - butyl hydroperoxide , and peroxides such as benzoyl peroxide or cyclohexanone peroxide , and suitable photochemically activated initiators include benzophenone , benzion ethyl ether , and 2 , 2 - dimethoxy - 2 - phenyl acetophenone . the amount of initiator used is generally about 0 . 01 to about 5 % by weight of the total polymerizable composition . the organic solvent used in the free radical copolymerization can be any organic liquid which is inert to the reactants and product and which will not otherwise adversely affect the reaction . suitable solvents include ethyl acetate and mixtures such as ethyl acetate with toluene or heptane with toluene and isopropyl alcohol . other solvent systems may also be used . the amount of solvent is generally about 30 - 80 % by weight of the total weight of reactants and solvent . in addition to solution polymerization , the copolymerization can be carried out by other well - known techniques such as suspension emulsion , and bulk polymerization . as described above , the preferred grafting technique involves copolymerization of methacrylic monomer , a , reinforcing monomer , b , and chemically tailored macromonomer , c , of controlled molecular weight . other grafting techniques can be employed , each providing a degree of predictability of the properties of the end product . one alternative technique involves preforming the methacrylic polymeric backbone , then copolymerizing this preformed backbone with cyclic siloxane monomer . another approach is to graft preformed monofunctional siloxane polymer to a preformed methacrylic polymeric backbone these and other polymer grafting techniques are described by noshay and mcgrath in block copolymers , academic press , new york ( 1977 ), pages 13 - 16 and in greater detail by battaerd and tregear in graft copolymers , j . wiley and sons , new york ( 1967 ). the copolymeric topically applied compositions of this invention in solution or dispersion are easily coated upon suitable body areas but not areas of the primary integumentary system , e . g ., hair on the scalp . the compositions maybe used on areas with vestigial hair ( such as the face and arms and legs ) but are not intended in the practice of the invention as primary treatments for hair . they are also not preferred for treatments in the lining of the eye or nasal passage . non - mucosal areas of the body of non - aqueous dwelling mammals are particularly preferred and fur treatments for non - human animals are also preferred ( dogs , cats , rabbits , etc .). the compositions of this invention may be coated by any of a variety of conventional coating techniques such as wiping , spraying , hand spreading , swab application , and the like . the topical application of medicaments to the skin has traditionally been done with the application of self - sustaining or self - supporting cohesive articles such as films , tapes , or plasters as a proposed improvement over direct applications of powders , ointments , creams , lotions or the like . it has been felt that these more substantial media provided a longer lasting and more controllable application of medicine to the skin or hair of a mammal . these medical applications suffer from distinct problems of their own , however . all of the films and tapes tend to be uncomfortable as they cannot completely conform with stretching , bending , or wrinkling which the exterior surfaces of bodies undergo during movement . the films , tapes and plasters are not cosmetically acceptable , especially if applied to the face and hands , which are exposed to view . films and tapes are easily and accidentially removed , in part or in whole , from the skin by inadvertent contact or perspiration occurring under the film or tape . this directly reduces the medical efficiency of the application . films and tapes can trap moisture against the surface which can be medically disadvantageous and can block oxygen penetration to the surface . the application of thin polymer films will not solve these problems because the films can be readily broken and delivery of the medicine can be interrupted . it has been found in the present invention that by selecting only appropriate proportion of medicaments and the non - pressure - sensitive adhesive polymeric binders in solutions , emulsions , or dispersions that an extremely effective topical application of medicaments , and skin treatments , and fur of hair treatments for animals other than humans may be performed . the proportions are selected , contrary to conventional wisdom , so that a non - cohesive , non - tacky coating of the binder and medicament is formed on the skin particularly in non - mucosal areas . medicaments according to the practice of the present invention are those compounds or materials which have a direct medicinal or neurological effect ( excluding alcohols ). materials which have a beneficial activity against the growth , propogation or survival of bacteria , fungi , or viruses or which are antihistamines , antioxins , anaesthetics , analgesics , antipruritics , vitamins , and antiinflammatants are included in the term medicaments . these materials are well known in the medical art and no exhaustive list is thought to be necessary . exemplary compounds include hydrocortisone acetate , undecylenic acid , tolnaftate , methyl salicylate , lidocaine , oxytetracycline . hcl , retinoic acid , minoxidil ®, etc . these medicaments may provide the medicinal activity at the site of application or upon absorption through the skin . these medicaments are combined in the critical proportions of this invention with the oil compatible non - pressure sensitive adhesives . pressure - sensitive adhesives are art recognized as a standard class of materials . these are adhesives which in dry ( substantially solvent free except for residual solvent ) form are aggressively and permanently tacky at room temperature ( e . g ., 15 . 0 ° to 25 . 0 ° c .) and firmly adhere to a variety of dissimilar surfaces upon mere contact without the need for more than manual pressure . they require no activation by water , solvent or heat in order to exert a strong adhesive holding force towards such materials as paper , cellophane , glass , wood and metals . they have a sufficiently cohesive holding and elastic nature so that , despite their aggressive tackiness , they can be handled with the fingers and removed from smooth surfaces without leaving a substantial residue ( cf . test method for pressure - sensitive tapes , 6th ed ., pressure sensitive tape council , 1953 ). pressure - sensitive adhesives and tapes are well known , and the wide range and balance of properties desired in such adhesives has been well analyzed ( cf . u . s . pat . no . 4 , 374 , 883 ; and &# 34 ; pressure - sensitive adhesives &# 34 ; in treatise on adhesion and adhesives vol . 2 , &# 34 ; materials &# 34 ;, r . i . patrick , ed ., marcel dekker , inc ., n . y ., 1969 ). the various materials and compositions useful as pressure - sensitive adhesives are available commercially and are thoroughly discussed in the literature ( e . g ., houwink and salomon , adhesion and adhesives , elsevier publ . co ., amsterdam , netherlands , 1967 ; handbook of pressure - sensitive adhesive technology , donates satas , ed ., vannostrand reinhold co ., n . y ., 1982 ). pressure - sensitive adhesives are generally chemically composed of rubber - resin materials , acrylic resins , polyurethane resins , silicone resins , and the like . among the various patent literature describing compositions and improvements in pressure - sensitive adhesive formulations are u . s . reissue pat . no . 24 , 906 ; u . s . pat . nos . 2 , 652 , 351 ; 3 , 740 , 366 ; 3 , 299 , 010 ; 3 , 770 , 708 ; 3 , 701 , 758 ; 3 , 922 , 464 ; 3 , 931 , 087 ; 4 , 012 , 560 ; 4 , 077 , 926 ; 4 , 387 , 172 ; 4 , 418 , 120 ; 4 , 629 , 663 ; and the like . these classes of rubber resin , acrylic , silicone and polyurethane pressure - sensitive adhesives as well as any other pressure - sensitive adhesives are not generally useful in the present invention . only non - pressure sensitive adhesives are used in the detailed proportions of the present invention , and non - tacky applications of medicaments are provided . the polymers useful in the present invention are oil compatible ( dispersible , swellable , or soluble in organic oils and non - polar solvents ) and generally are clearly hydrophobic in their properties . the molecular weight of the polymers used in the compositions may vary over a board range . the molecular weight must be suitably large to provide the requisite binding effect . the upper limit is determined only by formulation requirements . as the molecular weight increases , the polymers tend to become too viscous to formulate easily into cosmetically - appealing compositions . generally , polymers having a brookfield viscosity between 50 and 100 , 000 cps and preferably between 500 and 15 , 000 cps , when measured at 16 . 6 percent non - volatiles , will be useful in the compositions of the invention . the acrylate polymers useful in the compositions are insoluble in water and must have a solubility parameter between about 6 and 10 in poorly and moderately hydrogen bonding solvents . the method for determining solubility parameter ranges of polymers and an extensive list of solvents ( classified as either poorly hydrogen bonding , moderately hydrogen bonding , or strongly hydrogen bonding ) are described in polymer handbook ( edited by bandrup and immergut ), pages iv - 344 - 358 . acrylate polymers having the requisite solubility parameter will be soluble swellable or dispersible in the oil base of the compositions . the compositions of the invention are of three basic types , i . e ., oils , water - in - oil and oil - in - water emulsions . the oil formulations are prepared by mixing the oil base , polymer and active ingredient ( e . g ., medicament ) together and warming the mixture with slow agitation to about 140 ° f . the water phase ingredients , if part of an emulsion formulation , are combined and heated to 180 ° f . this phase is slowly added to the oil phase ingredients , also at 180 ° f , and the combination allowed to cool with agitation . the formulations generally contain about 0 . 5 to 10 percent by weight of the acrylate polymer , with the preferred range being from about 0 . 5 to 5 . 0 percent by weight . at levels below 0 . 25 percent , the polymer is less effective in holding a significant amount of the active ingredient ( e . g ., medicament ) on the skin when the skin is exposed to water . at levels above 10 percent , the formulation generally becomes sticky and develops an unpleasant feeling . the cosmetic oil base , if any , of the compositions may be solid or liquid , but the entire formulation should be somewhat fluid at skin temperatures for ease of application . fragrances , fillers , dyes , colorants , preservatives , antioxidants and other such material may be included in minor amounts in the compositions without effecting the substantivity of the composition . when applied to human skin , these products form films of the medicament on the skin surface . the polymer dispersed therein holds the medicament or chemical treatment onto the skin so that a significantly greater pharmacological or cosmetic benefit is provided than the composition without the polymer . as indicated above , the composition to be applied to topical areas of mammals ( generally non - water dwelling mammals ) comprises 0 . 25 - 10 % by total weight of polymer , preferably 0 . 5 to 5 percent by weight , and most preferably 0 . 5 to 2 % by weight of polymer per total weight of composition . the active ingredient or medicament may be present in a broader weight range of 0 . 1 to 50 % by total weight of the composition , preferably 0 . 25 to 20 % by weight , more preferably 0 . 5 to 10 % and most preferably 1 to 3 % by weight . the ratio of the polymer to medicament ( wt . polymer / wt . medicament ) should also be in the range of 1 / 5 to 1 / 50 to achieve the benefits of the present invention . these and other aspects of the invention will be shown in the following non - limiting examples . all polymer samples were prepared by the same general procedure . the polymerizations were carried out in ethyl acetate solution at 60 ° c . with benzoyl peroxide as the initiator . the composition of each of the examples is given in the table . also included in the table is relevant data such as the amount of solvent and initiator used in each reaction . a 16 oz narrow - mouth glass bottle was charged with the monomers , solvent , and initiator . the reaction solution was deoxygenated by four cycles that consisted of evacuation of the bottle for 5 - 10 minutes with a water aspirator followed by breaking the vacuum with nitrogen gas . the bottle was then sealed with a foil - lined metal cap . the polymerizations were carried out in an atlas launder - o - meter ™ for 40 - 48 hours . after the mixtures were cooled to room temperature , the samples were evaporated to dryness . __________________________________________________________________________examplesmacro -
