Theoretical Bases of Polymer Photodegradation and Photooxidation,
Abstract
The photodegradation and photooxidation of polymers are interrelated processes which occur simultaneously during the photoaging of polymers in the air. Only under laboratory conditions can one distinguish photodegradation from photooxidation by conducting reactions in an oxygen-free atmosphere. Polymers synthesized on an industrial scale are contaminated with various low-molecular compounds derived from the technological process (initiators, inhibitors, moderators, solvents, etc.). In addition, when such processes are carried out in an atmosphere of air, numerous carbonyl, carboxyl, hydroxyl, etc. groups form along the polymer chain. It is quite difficult and sometimes downright impossible to eliminate these impurities. For this reason, an examination of the issue of polymer photoaging should be multilateral.
