The mechanism of by-product formation in the reaction of a thiol antioxidant, 3,5-di-tertbutyl-4-hydroxybenzyl mercaptan (BHBM), with rubber latices is shown to involve two processes, viz dimerization of the intermediate thiyl radical to give disulphide (BHBDS) and the reaction of the intermediate q
