  • Publication number: 20190194424
    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.

  • Patent number: 10316005
    Abstract: The present invention relates to a process for the preparation of bis(dimercaptothiadiazole) (or bis-DMTD), more particularly of 5,5?-dithiobis(1,3,4-thiadiazole-2-thiol), said process being carried out in a single reactor and making possible a preparation with improved yields which is more respectful of the environment.
