Stearic and benzoic acids were heated with 2-bisbenzothiazole-2,2ะˆ-disulfide (MBTS)/sulfur/ZnO and tetramethylthiuram disulfide (TMTD)/sulfur/ZnO isothermally at 150ยฐC and in a DSC at 2.5ยฐC/min, in the absence of rubber. The acids readily reacted with ZnO, and at vulcanization temperatures, little o

Polyisoprene was vulcanized by 2-bisbenzothiazole-2,2ะˆ-disulfide (MBTS)/ sulfur and tetramethylthiuram disulfide (TMTD)/sulfur in the absence and presence of benzoic and stearic acids. It was found that the crosslink density of MBTS vulcanizates is halved by the addition of carboxylic acids and this
