Zusammenfassung:PROBLEM TO BE SOLVED: To provide a vulcanizing agent for improving reversion resistance, heat resistance, and dynamic low heat generation of rubber. SOLUTION: In a rubber composition, 0.5-20 pts.wt. of an alkyl bisthiocyanate represented by chemical formula 1: N≡C-S-R1-S-C≡N is mixed with 100 pts.wt. of rubber enabling sulfur vulcanization, wherein R1is a 3-8C straight chain saturated hydrocarbon group.
