Relationship of synthesis conditions, composition and properties of copolymers on the base of fluoromethacrylates
The copolymerization of 1,1,3-thrihydrofluoropropylmethacrylate, 1,1,5- thrihydroperfluoroamylmethacrylate, 1,1,5- thrihydroperfluoroamylacrylate with methylmethacrylate in the temperature range of 45-90єC has been studied. The changing character of given monomers copolymerization rate and forming copolymers composition has been found to depend on process temperature regime. The copolymerization constants r1 and r2 for binary systems have been determined. Rheological and thermo mechanical study of copolymer properties showed that the increasing of fraction of MMA units in the copolymer composition promotes the formation of polymer with more stiff- chain characteristics.
