Process for the preparation of diene rubber vulcanizates

摘要

Vulcanization of diene rubbers at a temperature of from 140 DEG to 200 DEG C. in the presence of 1 to 4.5 parts of a crosslinker having the formula s benzyl, in the simultaneous presence of a very small amount of sulfur and a small amount of a mercapto or sulfenamide accelerator or mixtures thereof affords elastomers having a previously unachieved outstanding ageing stability and reversion stability, after relatively short vulcanization times using economical amounts of chemicals while avoiding blooming phenomena in the vulcanizate.
