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.

A chlorinated polyethylene elastomer is made by mixing polyethylene with water to form an aqueous suspension of the polyethylene and simultaneously chlorinating and grafting a cure site on the polyethylene by mixing and heating the aqueous suspension containing a free radical initiator, gaseous chlorine and about 0. 1-1. 5 moles per kg of polyethylene of an alkyl or alkylaryl monester of butenedioic acid having the formulas ##STR1## or mixtures thereof, where R. sub. 1 is an alkyl or alkylaryl group having from about 8-20 carbon atoms and R. sub. 2 and R. sub. 3 are hydrogen, chlorine or an alkyl group having from about 1-4 carbon atoms.

Thermoplastic polymer alloy compositions are provided consisting of a blend of polypropylene, ethylene copolymer ionomer resin, ethylene/glycidyl acrylate or methacrylate copolymer, and uncrosslinked ethylene propylene rubber. The compositions are particularly useful in applications where a wide range of temperature and abrasive conditions are encountered.
