Natural rubber vulcanizates of two formulations, with sulfur/ N ‐cyclohexyl‐2‐benzothiazolesulfenamide (CBS) and tetramethylthiuram disulfide (TMTD), respectively, were analyzed by pyrolysis gas chromatography. A sulfur‐selective flame‐photometric detector was utilized. The main pyrolysis products were identified as CS 2 and some thiophenes. The yields of the pyrolysis products from the two types of rubber were very different. The yields also varied with the curing time of the rubbers.
