Abstract :
The TSDC (thermally stimulated depolarization current) method was used to study the effect of polymer structure on electrical properties for poly(phenylquinooxaline). Seven relaxation regions were distinguished in the TSDC spectrum. The probability of observing the regions depends strongly on the degree of annealing of the samples. The TSDC in PETP is also found to be influenced by the physical structure. The TSDC spectrum of pure and saponificated poly(methylmethacrylate) was investigated. Three relaxation regions were observed: the beta - and alpha -relaxation and a space charge relaxation.
