Abstract

The evolution of the gamma relaxation along the early stages of the thermo-oxidation of two isotactic polypropylenes (i-PP) has been studied. It has been found that regardless of their different thermal stability, they show a similar disappearing of the gamma relaxation as soon as the induction period ends. The features of that disappearance and its correlation with some chemical and structural changes on oxidising are discussed. (C) 1999 Elsevier Science Ltd. All rights reserved.
