Abstract

Polyester films which comprise a stabilizer for inhibiting oxidative degradation, at least some of which has been covalently incorporated into the polymer chain of the polyester through polycondensation during formation of the polyester, have not only high resistance to oxidation but also very few surface defects and high stability during processing, and are suitable not only for use as a packaging material but for a wide variety of other technical applications.
