Electrical conduction and space charge distribution in oxidized low-density polyethylene (samples A1-A6) and copolymers of ethylene and carbon monoxide (samples B1-B3) with different carbonyl contents have been studied. A V-shaped dependence of conduction current on carbonyl content was observed for samples A1-A6, while the current decreases monotonically with an increase in carbonyl content for samples B1-B3. The effect for polar groups on electrical conduction is discussed, focusing on their bonding forms in polymer molecules.
