The temperature dependence of conductivity of partially dehydrochlorinated PVC films, containing in their macromolecules chains of polyene-conjugated bonds (PCB) and representing copolymer PVC-Polyacetylene. In samples with excess of some "threshold" concentration of PCB with increasing temperature it was found conductivity switching on 10 -11 orders of magnitude. Instability of states with high conductivity in the temperature range which depends on the concentration of PCB was detected. Qualitatively, the increase of concentration of PCB was monitored by fixing the fluorescent and absorption spectra.
