When silvery films of the semiconducting polymer, cis-‘polyacetylene,’(CH)x, are used as the anode in the electrolysis of aqueous KI solutions or methylene chloride solutions of Bun4N+ClO4–, films of (CHIy)x and CH(ClO4)yx, respectively, are obtained which, for the compositions CHI0·07x and CH(ClO4)0·0645x have high conductivities characteristic of the metallic state.
