## SYNOPSIS 2,3-Dimethyl-2-butene (TME) was used as a model for polyisoprene in a study of zinc dimethyldithiocarbamate (Zn,(dmtc),) -accelerated sulfur vulcanization. Mixtures of T M E and curatives were heated in sealed tubes to 130°C for various times and the contents analyzed by HPLC. Zn2(dmtc

Sulfur-free thiuram vulcanization has been investigated a t temperatures from 160" to 190°C over 0.5 to 600 min. Continuous measurements in a W R E M O curemeter were used to estimate the extent of crosslinking, which was plotted against cure time. Simultaneously the values of the network chain dens
Mixtures of tetramethylthiuram disulfide (TMTD)/ZnO and TMTD/sulfur/ZnO were heated in a DSC to various temperatures. Zinc dimethyldithiocarbamate (Zn,(dmtc)J formed only in undried TMTD/ZnO mixes, the reaction being catalyzed by water on the ZnO surface. The presence of ZnO delays the decomposition
