Abstract

Disclosed is a process for crosslinking copolymers of ethylene and acrylic esters by converting some of the ester groups to ester or amide groups which contain unsaturation, and then sulfur or peroxide curing the resulting polymers. The resulting crosslinked polymers often have excellent vulcanizate properties, and are useful especially in elastomeric form as seals and gasket.
