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.

Process for crosslinking of ethylene/acrylic ester copolymers

A process for reducing the carbonyl group of a polyketone consisting of a carbon monoxide ethylene-based copolymer, comprising reacting a blend of carbon monoxide ethylene-based polymer with a metal alkoxide in a molten condition in proportions to provide a novel polyalcohol. This chemical modification changes the properties of the carbon monoxide ethylene-based polymers and renders them eligible for uses for which the original polymers were not or not very suitable.
