摘要：

This paper deals with the degradation processes occurring during polymer processing. Some general aspects of polymer processing are first recalled. Then, oxidation mechanisms and kinetics are evoked and the main processing methods are compared from this point of view. Temperature-molar mass maps allow to define a processability window and to envisage ways to widen this window. The final chapter is devoted to a case study: the PET processing, which is characterized by an especially complex combination of degradation processes.
