摘要：

This work deals with a comparison of data obtained from differential scanning calorimetry (DSC) and thermally stimulated depolarization current (TSDC) investigations. Measurements were performed on various poly(ethylene terephthalate) films: a wholly amorphous, a thermally crystallized and drawn samples. For each specimen, the TSDC complex spectra, resolved into elementary ones, led to the determination of the classical compensation temperature (T-c). The glass transition temperature (T-g) and the fictive equilibrium temperature (T-f) were determined by means of DSC. It appears that T-c is different from T-g and very close to T-f.
