The temperature dependence conductivity of heat-treated PVC films containing conjugated carbon-carbon double bonds in the chain of their macromolecules, which are copolymers of polyvinyl chloride-polyacetylene, was studied. In samples with an excess of the threshold concentration of conjugated double bonds of carbon and their associated charge carriers (π-electrons), conduction switches were detected by 10 orders of magnitude with increasing temperature. The instability of the state with semiconducting conductivity in the temperature range, the width of which depends on the concentration of conjugated double carbon-carbon bonds and the associated charge carriers, is found. A qualitatively increase in the concentration of conjugated carbon – carbon double bonds was monitored by fixing the photoluminescence spectra and infrared absorption spectra.
