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 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
