Thermally stimulated currents (TSCs) were examined in a temperature range from room temperature to 170 °C for positively corona‐charged polypropylene films which were, before charging, uniaxially cold drawn to different drawing ratiosDup to 3.5 or were annealed at different annealing temperaturesTaafter drawn toD=3. Two main TSC bandsP+1andP+2were observed around 60 and 140 °C, respectively. The peak temperature ofP+1strongly depended onDandTa: It shifted toward higher temperature by drawing while it turned to shift toward lower temperature by annealing.
