    摘要: A process for the production of diorganodisulfides by oxidation of meraptans in which the mercaptan is reacted with a halogen compound capable of releasing at least one halogen atom and taking up a hydrogen atom instead, the reaction being carried out at 0.degree. to 100.degree. C. in the presence of base and, optionally, a phase transfer catalyst.

    摘要: 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.
