Abstract
TSC spectra of amorphous and semicrystalline PET annealed at 65 °C and 90 °C for the various duration times have been measured respectively. The drastic effect of sub-Tg on the g amorphous region is observed. The max current of the thermo-relaxation of frozen-in dipoles decreases with increasing of storage time. DSC curves, crystallinity and density of the amorphous specimens were measured. The transition of the amorphous PET from the ductile to brittle fracture appeared at the same storage time as in TSC measurement. It was illustrated that TSC is a sensitive and powerful method for investigating the sub-Tg storage.
