The sulfur vulcanization of NR by a MBT-TMTD mixed accelerator system both in the presence and absence of ZnO and stearic acid with or without DCP has been studied. The rate of decomposition of DCP in the presence of both MBT and T M T D is quite similar to that in the MBT system alone. The reductio

The effect of benzoic and stearic acids on 2-bisbenzothiazole-2,2Π-disulfide (MBTS)-and tetramethylthiuram disulfide (TMTD)-accelerated sulfur vulcanization of polyisoprene compounds, containing ZnO, was studied at 150Β°C. In the presence of ZnO, the acids are rapidly converted to their zinc salts th
Polyisoprene (IR), poly(styrene-cobutadiene) (SBR) and IR-SBR blends were vulcanized with tetramethylthiuram disulfide/sulfur in a differential scanning calorimeter (DSC) at a programmed heating rate and isothermally in a press at 130 o C. The reaction was stopped at various stages, and the crosslin
## 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
The thermal stability of N,NΠ-dipentamethylenethiuram disulfide (CPTD) and tetramethylthiuram disulfide (TMTD) with respect to thiourea formation was compared. CPTD is stable at 120Β°C but decomposes to N,NΠ-dipentamethylenethiourea (CPTU) at vulcanization temperatures (140Β°C), while TMTD is stable t
