Bisdiazonium chlorides of benzidine and 3, 3′-disubstituted benzidines were isolated as needle-like crystals, and they were complexed with CuCl in pure water. The complex suspension was heated at 70°C in the presence of various amounts of vinylimidazole to produce copolymers which were composed of substituted biphenyls and imidazolyl groups. These copolymers were insoluble in nonpolar solvents but soluble in DMF, THF and ethanol. Viscosity-concentration profile of DMF solution of the copolymer revealed an anomalous peak in a large dilution range as was observed in the viscosity curve of substituted polyphenylene. The appearance of anomalous peak was explained in terms of a change in solvent inclusion ratio in the Fickentscher-Mark equation. Further, these copolymers revealed a high catalytic activity for the solvolysis of acetylbenztriazole in ethanol-water. The catalytic reactions were discussed by calculating their kinetic parameters.
