Abstract

The crosslinking of chlorinated polyethylene with 2,5-dimercapto-1,3,4-thiadiazole in the presence of a basic substance may be carried out easily and leads to improved vulcanizate properties if amido amines, for example tetraethylene pentamine distearate, are used as the basic substances.
