Abstract

The temperature dependence of the conductivity of heat-treated polyvinyl chloride films containing conjugated double carbon–carbon bonds in the chain of its macromolecules and representing polyvinyl chloride–polyacetylene copolymers is studied. The samples with an above threshold concentration of conjugated carbon–carbon double bonds and associated charge carriers (π-electrons) exhibit changes in the conductivity by ten orders of magnitude as the temperature increases. It is found that the semiconducting state of the copolymer in the temperature range, the width of which depends on the concentration of conjugated double carbon–carbon bonds and associated charge carriers, is unstable. Qualitatively, the increase in the concentration of conjugated double carbon–carbon bonds was controlled by recording photoluminescent spectra and infrared absorption spectra.
