Abstract：1, 6 - bis(natriumthiosulfate) hexane was prepared using 1, 6 - dichlorohexane and sodium thiosulfate, after that a new vulcanizator 1, 6- bis (diethylthiocarbamoyl - disulfide) hexane was prepared and characterized by IR and MS. The mechanism of improving the reversion of rubber composition was discussed, and the application tests were carried on. The results showed that reversion resistant and dynnmic fatigue property of rubber vulcanized by new vulcanizator were excellent.
