Abstract

Polyolefins, which normally undergo high temperature manufacturing and fabrication operations, are susceptible to oxidation during each stage of their lifecycle. Stabilisers and antioxidants are used to inhibit the oxidative damage that is ultimately responsible for loss of physical properties, embrittlement and premature failure. Environmental awareness and health and safety considerations have spurred intense searches for new approaches to procure improved, safe, and more efficient antioxidants and stabiliser systems for polymers. Current activities have concentrated on two approaches: the first advocates the use of biological (naturally occurring) antioxidants, and the second relies on the use of reactive antioxidants that are chemically attached onto the polymer backbone for greater permanence and safety. Stabilisation of polyolefins through the use of vitamin E and some reactive, non-migratory antioxidants is the subject matter of this chapter.
