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

New thermally stimulated depolarization currents (TSDC) results on LLD polyethylene functionalized with diethylmaleate polar groups are precisely computer fitted with the direct signal analysis technique. It is shown that the TSDC spectrum consists, with increasing temperatures, of a sub-y peak, a s
Electrical properties of poly (2,6-dimethyl-1,4-phenylene oxide) (PPO) have been studied by measuring thermally stimulated discharge currents. Depolarization behavior of poled PPO film exhibits temperature-and time-dependent single relaxation around 468 K which is attributed to dipole reorientation.
A thermally induced conformational change of zwitterionic groups of two polymers has been observed by thermally stimulated depolarization currents. Different dipole moments of the two conformations is a prerequisite. The appearance of peaks of opposite sign confirms the process. Giant dielectric con
