Abstract
Abstract Compositions containing copolymers of epihalohydrins, an unsaturated epoxy comonomer, and optionally, ethylene oxide are readily cured to useful articles with peroxides when such compounds contain a polyacrylic acid ester of a polyol and Group IA, IIA, or IVA compound. Covulcanized compositions are prepared from mixtures of the epihalohydrin and epoxy copolymers with peroxy vulcanizable polymers.
