Sulfenamide, rubber vulcanization accelerator containing the sulfenamide, and method for producing the same

摘要

[Topic] it possesses the slow-acting property for the sufficient vulcanization reaction, at the same time does not generate carcinogenic nitrosamine and it offers the sulfenic amide vulcanization accelerator which does not have the problem for environmental hygiene such as organism concentrated characteristic.[Solution expedient] the vulcanization accelerator and its manufacturing method which for the rubber contain N alkyl N t butyl benzo thiazole 2 sulfenic amide and this chemical compound which are shown with formula I. Conversion 1 [R shows the methyl group, the ethyl group, the n propyl basis or the n butyl basis]
