ABSTRACT
Polypropylene (PP) is today one of the most widely used of all of the commodity polymers. The versatility of this material arises from the cheap petrochemical stocks as raw materials, the sophisticated and efficient catalytic polymerization processes, and the ease of processing of the final polymer as a fabricated article by injection molding or as a textile by spinning (1). This success has occurred in spite of the polymer being one of the most oxidatively unstable of the polyolefins and is a reflection of the extent to which an understanding of the oxidative degradation of the polymer has led to strategies for stabilization (2,3).
