## Abstract Tetramethyl thiuram disulfide, which functions as an inhibitor of the zinc dialkyldithiocarbamateβaccelerated sulfur vulcanization, has been investigated by Mooney scorch measurements at 120Β°C and continuous measurements in a Vuremo curometer at temperatures from 100 to 140Β°C. The inhib
Polyisoprene was vulcanized by 2-bisbenzothiazole-2,2Π-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
Polyisoprene was vulcanized with binary accelerator systems comprising mixtures of the zinc salts of tetramethylthiuram disulfide (TMTD) and 2-mercaptobenzothiale (MBT). Samples were heated in a DSC at a programmed rate, the reaction was stopped at points along the thermal curve, and the system was
Polyisoprene was vulcanized with the binary accelerator system tetramethylthiuram disulfide-2-mercaptobenzothiazole (TMTD-MBT) in the absence of ZnO. Samples were heated in a DSC at a programmed rate, the reaction was stopped a t points along the thermal curve, and the system was analyzed. Extractab
