Abstract

The synthesis of thiol-adduct antioxidants by a mechano-chemical procedure in elastomers is described. The yields of polymer-bound antioxidants so formed increase with increasing antioxidant loading and for most unsaturated polymers an optimal yield is observed at 20–30% loading. Bound antioxidant concentrates made by this procedure have been used as additives in a range of elastomers and it has been demonstrated that an adduct concentrate (masterbatch) in one polymer (e.g. EPDM) can be used in a range of other polymers without sacrificing efficiency.
