ABSTRACT:
A process for the production of improved vulcanizates is described wherein a carboxylated butadiene-acrylonitrile polymer is compounded with an epoxidized hydrocarbyl compound which on vulcanization yields a vulcanizate having generally improved strength properties and reduced compression set. Such vulcanizates can advantageously be used as O-rings, gaskets and the like.
