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 (To). The glass transition temperature (Tg) and the fictive equilibrium temperature (Tf) were determined by means of DSC. It appears that Tc is different from Tg and very close to Tr.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
