Poly(isoprene-co-isobutylene) (IIR or butyl) and chlorinated poly(isopreneco-isobutylene) (CIIR or chlorobutyl) compounds containing combinations of zinc dimethyldithiocarbamate [Zn 2 (dmtc) 4 ], tetramethylthiuram disulfide (TMTD), sulfur, and ZnO were vulcanized at 150Β°C, the reaction was stopped
## 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
