Radiation Crosslinking of Neoprene W with Diallyl Etherofmaleic Acid and Epoxy Resins

Discusses the use of technological aspects and radiation crosslinking Neoprene W in the presence of a diallyl ester of maleic acid (DAEMA) and epoxy resin (ED-5) in the presence of metal oxides. With the help of physico-chemical and spectral methods shows the variation in the molecular structure Neoprene W in the presence of DAEMA and ED-5 after irradiation with γ-rays of 500 kGr. With analysis method of Sol-gel for each test system determined the radiation-chemical yield (RCY) and the emergence of cross-linking of cross-links in the elastomer. The dependence of the crystallinity index of the degree of stretching for Neoprene W, irradiated at 500 kGy was defined. It was found that at the radiation vulcanization Neoprene W in the presence of a bifunctional bonds epoxy resin weakly has a decisive influence on the kinetics of the process and yield crosslinking. It is shown that above 1500 kGy irradiation in the filled Neoprene observed destruction in the elastomer chain, resulting in deterioration of physical and mechanical properties of the vulcanizates.
