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.

Disclosed is a process for the preparation of polyamide polymers via prepolymer formation in a reactor system comprising a reactor, flasher and separator, crystallization of the prepolymer under controlled temperature conditions and the subsequent conversion of these crystallized prepolymers to high molecular weight polymer.
