SULFUR-VULCANIZABLE BLENDS OF ETHYLENE-VINYL ACETATE COPOLYMER ELASTOMERS AND POLYACRYLATE ELASTOMERS

摘要

SULFUR-VULCANIZABLE BLENDS OF ETHYLENEVINYL ACETATE COPOLYMER ELASTOMERS AND POLYACRYLATE ELASTOMERS Polyacrylate-containing elastomers, having improved tensile strength and hardness upon vulcanization, comprise blends containing about 35 to 65 percent, by weight, of a sulfur-vulcanizable graft elastomer having a major proportion of ethyl acrylate and a minor proportion of an ethylenically unsaturated comonomer which contains a cure-site for sulfur vulcanization, grafted onto an ethylene-vinyl acetate copolymer, and about 65 to 35 percent, by weight, of a sulfur- vulcanizable polyacrylate elastomer.
