Unsaturated hydantoin derivatives of the formula <IMAGE> +tr <IMAGE> WHERE R1 and R2 are alkyl, R3 is vinyl, allyl, alkylene, substituted alkylene or polyvalent aralkyl, R4 is vinyl or allyl and n is 1 to 3, are coagents for curing polymeric compositions to improve their physical, chemical and electrical properties. These coagents are particularly useful in crosslinking PVC, polyethylene, chlorinated polyethylene and poly(ethylene/vinyl acetate) compositions.
