✦ Synopsis

Thermally stimulated depolarization current (TSDC) of PVC containing 4-mercaptoacetamidodiphenylamine was studied. The current peak height (arelaxation peak), maximum temperature, and activation energies were found to be influenced by the additive. The results suggest that no internal plasticization occurs in the system. The a-relaxation broadening was found to originate from a distribution of activation energies according to the rotation of the amide group of the additive.
