A study has been made of the dc volume resistivity of plasticized PVC using a guarded‐electrode system in a sensitive vibrating capacitor–electrometer circuit. Transient effects were found to be pronounced in all but the least plasticized compositions, and the behavior in general was non‐Ohmic. The resistivity decreases with plasticizer concentration and with temperature; an Arrhenius‐type relationship is observed and resistivity undergoes an inflection at the glass transition temperature. The mechanism of conduction appears to be electrolytic rather than charge injection or semiconduction.
