The thermally stimulated current-thermal sampling (TSC-TS) technique was used to study the broadened glass transition in conventional ''atactic'' poly(vinyl chloride), PVC. The activated parameters obtained from the TSC-TS data, mainly the apparent activation energy (E a ), characterize the breadth

Semicrystalline fluoropolymers including poly(tetrafluoroethy1ene) (PTFE), a 8 mol % hexafluoropropylene (HFP)/92% T F E random copolymer (FEP), and poly(viny1 fluoride) (PVF) were studied using thermally stimulated current depolarization (TSC), ac dielectric, and other thermal analysis techniques.
The relaxation mechanisms present in a side-chain liquid crystalline polymer have been studied by Thermally Stimulated Depolarization Currents (t.s.d.c.), in a wide temperature range covering the glassy state, the glass transition region, and the liquid crystalline phase. The thermal sampling proced
Molecular motion and relaxation studies using a thermal windowing thermally stimulated depolarization current (TW-TSDC) were performed for aliphatic polyureas 7 and 9. Global thermally stimulated depolarization current gave three characteristic major peaks corresponding to the β£, β€, and β₯ relaxation
