## Abstract **Summary:** Isoconversional kinetic analysis involves evaluating a dependence of the effective activation energy on conversion or temperature and using this dependence for making kinetic predictions and for exploring the mechanisms of thermally stimulated processes. The paper discusses

Thermally stimulated depolarization currents (TSDC) and differential scanning calorimetry (DSC) are performed on thermoplastic polyesters and dimethacrylate resins over temperature ranges covering the β£ and β€ relaxation regions. The noncooperative β€ relaxation is characterized by a continuous variat
The thermally stimulated depolarization currents (TSDC) from atactic polystyrene and d.c. conductivity of the same material have been studied over the temperature ranges 20~395 K and 363-393 K respectively. TSDC spectra are complex and consist of four peaks, ill,/32, f13 (f13 of reduced intensity) a
