Abstract
The present invention relates to the field of vulcanization of unsaturated polymers, in particular halogenated, and more particularly chlorinated, unsaturated polymers, such as, for example, polychloroprene, using as vulcanization agent a mixture of bis(2,5-dimercapto-1,3,4-thiadiazole) and at least one organic base. The present invention relates to the process for vulcanization of said polymers with said vulcanization mixture.
Claims16
A composition for the vulcanization of unsaturated polymers, comprising a mixture of bis(2,5-dimercapto-1,3,4-thiadiazole) and at least one organic base.
The composition according to claim 12, wherein the at least one organic base is a guanidine substituted by one or more aryl groups.
A process for the vulcanization of an unsaturated polymer, comprising:
- mixing the unsaturated polymer with a mixture of bis(2,5-dimercapto-1,3,4-thiadiazole) and at least one organic base, and
- vulcanizing the unsaturated polymer.
