Abstract :
In order to understand the nature of the origin of the released current in the temperature range from room temperature up to 220 °C, TSDC and the isothermally final discharging current (IFDC) have been measured, in vacuum and in different ambient gases for PET specimens. The behavior of the samples polarized in oxygen, in nitrogen and in ambient air was analyzed. The contribution of the heterocharge, the homocharge and the absorbed gases to the measured current is analyzed
