VULCANIZATION ACCELERATOR USING AMINE

摘要

PROBLEM TO BE SOLVED: To provide a vulcanization accelerator which is useful for accelerating the vulcanization of a diene rubber and yields a vulcanizate with physical properties equal or superior to those given by a vulcanization accelerator on the market; and a rubber composition which contains the vulcanization accelerator and yields a vulcanizate useful in the rubber industry. SOLUTION: The rubber composition is prepared by compounding 100 pts.wt. natural rubber and/or synthetic diene rubber with 1-10 pts.wt. vulcanization accelerator represented by the formula: H2N-(CH2)n-NH2R-NH2(wherein n is an integer of 8-16; and R is an 8-25C linear or branched alkyl group).
