Abstract

The performance of polymer artifacts is adversely affected if degradation occurs during the various stages of polymer manufacture, fabrication, and subsequent exposure to the environment. Molecular oxygen is the major cause of polymer degradation and is responsible for the ultimate mechanical failure of polymer artifacts. The deleterious effect of molecular oxygen is accelerated by many other factors: sunlight; heat; ozone; atmospheric pollutants; water; mechanical stress; adventitious metal and metal ion contaminants.
