Abstract
Recent research has shown that a variety of antioxidants have the ability to trap alkyl radicals under conditions of rapid radical generation and/or low oxygen pressure chain-breaking acceptor (CB-A) process. When the antioxidant has a well characterised oxidised and reduced form the resulting redox couple may give rise to a catalytic antioxidant effect under certain conditions. Such a CB-A/CB-D catalytic effect has been known to operate in polypropylene during processing and in rubber during fatiguing. It is also believed to account for the high fatigue resistance of sulphur vulcanisates.
