ABSTRACT OF THE DISCLOSURE Halopolymers, such as chlorinated polyethylene, are uniquely vulcanized by heating a curable mixture including the halopolymer and a 1,3-diaminopropane or salt thereof. A preferred mixture further includes an acid acceptor, such as calcium oxide or calcium hydroxide, and sulfur or a sulfur-containing compound. The scorch safety and shelf life of such compositions are further imprcved by adding a minor amount of a mixture of N-(cyclohexylthio)phthalimide and N-nitrosodiphenyl- amine.
