Sulfur-vulcanizable chlorinated polyethylene-acrylate copolymer graft elastomer

摘要

Chlorinated polyethylene elastomers are rendered sulfur-vulcanizable by the incorporation thereinto of a copolymer comprising one or more acrylic acid esters, or one or more acrylic acid esters and acrylonitrile, and an ethylenically unsaturated comonomer containing a cure site for sulfur vulcanization. Upon vulcanization, the elastomers exhibit excellent resistance to hydrocarbon oils.
