Abstract
The aim of this work is to study physical ageing by ThermoStimulated Current (TSC) experiments. The polymers under investigation are amorphous and semi-crystalline PET. The results presented here focus on the glass transition. The question of the effect of ageing on the constrained amorphous chains in the case of semi-crystalline PET is put forward
