Abstract :
Summary form only given, as follows. The effect of the Polstat 12-14 antistatic agent on electrical conductivity, thermally stimulated currents and decay of surface charges in polypropylene foil was investigated. It was found that the antistatic dopant increases electrical conductivity in the temperature range 293-380 K. Conductivity as a reciprocal function of temperature shows two activation processes. The values of activation energy computed from the conductivity characteristics and from the TSD spectra are compared. It was found that the antistatic agent produces deep traps for the injected charge carriers and causes an increase of their relaxation times.<>
