Abstract

Experimental results on anomalous conductivity in specifically synthesized copolymer films are analyzed. Polyacetylene molecular fragments with variable concentration are introduced into polyvinylchloride macromolecules. It is shown that such samples exhibit spontaneous and stimulated conductivity jumps by 13 orders of magnitude and the lifetime of such states may range from several minutes to a day. A qualitative model is proposed to describe the anomalous behavior of the polyvinylchloride composite including effects that provide stabilization of the high-conductivity states, conditions for development of instability in the transitions between the states, and the reasons for long-lived high-conductivity state even in the absence of external voltage. Simple numerical estimations that prove the proposed effects are considered.
