Time dependent collected extracts of the vulcanizates were analyzed by means of HPLC-MS and HPLC-UV. The MS-analysis shows the existence of dibenzothiazolyl-polysulfides during the scorch period. Quantitative analysis of the soluble reaction products demonstrates the influence of the sulfur-accelerator-ratio to the dispoportion of the accelerator and the rate of the crosslinking reaction ER -
