Poly(viny1 alcohol) films were polarized at different electrical field strengths and temperatures. The peak temperature of the TSDC spectra shifted to higher values with increasing polarizing field strength and polarizing temperature. The activation energies and relaxation parameters of the process were evaluated. Based on the results, the origin of TSDC was attributed to space charge polarization with some contribution of dipole orientation. Thermisch stirnulierte Depolarisationsstrome in Poly(vinylalkoho1)-FilmenPoly(vinylalkohol)-Filme wurden bei unterschiedlichen elektrischen Feldstarken und Temperaturen polarisiert. Die Peaktemperatur der TSDC-Spektren verschob sich mit steigender Polungsfeldstarke und Polungstemperatur zu hoheren Werten. Die Aktivierungsenergien und die Relaxationsparameter des Prozesses wurden ermittelt. Auf Grund der Ergebnisse wurde der Ursprung der TSDC der Raumladungspolarisation mit einem geringen von der Dipolorientierung herriihrenden Beitrag zugeordnet.
