Abstract: A cross-linked polymer of an epihalohydrin prepared by heating a polymer of an epihalohydrin in the presence of a metal salt of ethylene-bisdithiocarbamic acid having the following formula:

Wherein symbol M stands for a divalent metal atom in the amount of from 0.1 to 10 parts by weight based on 100 parts by weight of the polymer of epihalohydrin, said epihalohydrin polymer being selected from the group consisting of polymers of epihalohydrin, copolymers of epihalohydrin with alkylene oxides, and mixtures containing other sulphur vulcanizable rubbers of not more than 50 percent by weight based on the weight of the mixture of the sulphur-vulcanizable rubbers with these homo- or co-polymers, and a process for preparation said polymer.
