✦ Synopsis

The course of cyclic voltatntnetric curves on a polyacetylene electrode was calculated on the assumption that the current is controlled by the rate of charge transfer and ohmic effects occurring in both the solid and liquid phases. The anodic branches of the voltammograms obtained on polyacetylene electrodes in 1 M LiClO, in propylene carbonate correspond roughly to the calculated curves, whereas the cathodic peaks are lower than calculated and the form of the cathodic branches suggests a complicating effect of solid-state diffusion of charge carriers on the cathodic current. The magnitude of the diffusion coefficient is discussed.
