摘要：
The dependence of the properties of a polypropylene blend with hydrogenated styrene-butadiene-styrene block copolymer, prepared under the conditions of dynamic vulcanization, on the concentrations of the peroxide and various vulcanization coagents (triethylene glycol dimethacrylate, triallyl cyanurate, triallyl isocy-anurate) was studied. The influence of the kind and concentration of the peroxide and coagent on the deformation and strength properties of the thermoplastic vulcanizate obtained was accounted for by the experimental data on variation of the gel fraction content of the mixture, vulcanization network density, and degree of crystallinity and molecular mass of polypropylene. The possibilities and conditions for reducing the compression set and enhancing the oil resistance of the thermoelastoplastic were determined.
