Dielectric properties of polyvinyl chloride films (TK 800 and TK 1000 films) prepared by the solvent cast method, were measured in the frequency range of about 0.1 Hz to 3 MHz. The dielectric loss factor e″ was found to be extraordinarily great at very low frequencies, and thus was corrected by ionic conduction. The dispersion observed at very low frequencies was quite different from that at high frequencies in the cases of TK 800 films containing 20 and 30% of plasticizer (DOP) and TK 1000 films containing 10 and 20% plasticizer. The discussion on this result was based on the effects of addition of plasticizer, the free-space in polymer films and the intertwining polymer chains in the process of dissolution concerning the dielectric properties of polyvinyl chloride films.
