Abstract A variety of chemical reactions lead to the oxidative deterioration of polymers upon processing and during end‐use of plastic articles. To inhibit the autoxidation cycle, stabilizers interfering at the various steps of the degradation are needed. Complex stabilizer systems which are able to suppress oxidative degradation have been developed recently. Special emphasis is given to radical scavenging, including alkyl radicals. UV absorbers with inherent photostability have led to an enhanced stability of polymers, such as engineering thermoplastics.
