    摘要: Unsaturated hydantoin derivatives of the formula ##STR1## where R.sub.1 and R.sub.2 are alkyl, R.sub.3 is vinyl, allyl, alkylene, substituted alkylene or polyvalent aralkyl, R.sub.4 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.
