Abstract
The cross-linking of halogenated polymers such as chlorinated polyethylene with bis-(2,5-dimercapto-1,3,4-thiadiazole) in the presence of a basic substance may easily be carried out and leads to improved properties of the vulcanisate, in particular when amidamines such as, for example, tetraethylene pentamine distearate are used as basic substances.
