VINYLOX IS EFFICIENT DILUENT OF EPOXY COMPOSITIONS
The results of research of the effect of vinylox being a high-efficient bifunctional monomer of 2-(vinylox)-etoxymethylxyran as a diluent of epoxy compositions have been presented in the paper. Vinylox has been demonstrated to provide more profound diluting effect in comparison with a conventional diluent - cresyl glycedine ether of UP-616. The differential scanning calorimetric method has determined that vinylox addition gives rise the thermal effect and temperature of reaction onset of the epoxy composition hardening. The strength dependences at tension, modulus of elasticity and adhesion strength at breaking-off vinylox concentration have got an extreme effect with maximum of properties at the diluent proportion 5-10 mass per hour. Breakage strain, destruction operation, shear strength of adhesive joints constantly rise during the whole investigated rate of vinylox but the glass transition temperature constantly decreases with elevation of diluent proportion. The findings of the investigations of dynamic and mechanical properties point at the considerable increase of dynamic modulus of elasticity at the glass structural state of a polymer during vinylox injection. The effect is connected with the formation of the additional chemical and physical bonds due to their greater mobility at vinylox presence.
