The thermal stability of N,NЈ-dipentamethylenethiuram disulfide (CPTD) and tetramethylthiuram disulfide (TMTD) with respect to thiourea formation was compared. CPTD is stable at 120°C but decomposes to N,NЈ-dipentamethylenethiourea (CPTU) at vulcanization temperatures (140°C), while TMTD is stable t

Polyisoprene was vulcanized by 2-bisbenzothiazole-2,2Ј-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
