SULFENAMIDE, VULCANIZATION ACCELERATOR CONTAINING THE SULFENAMIDE FOR RUBBER, AND PROCESS FOR PRODUCING THE SAME

A sulfonamide-based vulcanization accelerator is provided which acts sufficiently slowly on a vulcanization reaction, generates no carcinogenic nitrosamine, and is free from hygienic or environmental problems such as bioaccumulation. Also provided is an N-alkyl-N-t-butylbenzothiazole-2-sulfenamide r...

Beschreibung
Zusammenfassung:	A sulfonamide-based vulcanization accelerator is provided which acts sufficiently slowly on a vulcanization reaction, generates no carcinogenic nitrosamine, and is free from hygienic or environmental problems such as bioaccumulation. Also provided is an N-alkyl-N-t-butylbenzothiazole-2-sulfenamide represented by formula (I). The vulcanization accelerator for rubbers contains this compound. Furthermore provided is a process for producing the same. [Chemical formula 1] [R represents methyl, ethyl, n-propyl, or n-butyl.] L'invention concerne un accélérateur de vulcanisation à base de sulfonamide qui agit suffisamment lentement sur une réaction de vulcanisation, qui ne génère pas de nitrosamine carcinogène et qui est exempt de problèmes d'hygiène ou environnementaux tels que la bioaccumulation. L'invention concerne également un N-alkyl-N-t-butylbenzothiazole-2-sulfénamide représenté par la formule (I). L'accélérateur de vulcanisation pour caoutchoucs contient ce composé. En outre, l'invention concerne un procédé pour produire celui-ci. [Formule chimique 1] [R représente méthyle, éthyle, n-propyle ou n-butyle.]
