Study of new modifications of poly(p-phenylene) synthesis via oxidative polycondensation

The results of recent studies of polyphenylene synthesis are summarized. Th e experimental results about the role of the AlCl3 quality, new catalysts, and solvents to obtain high-molecular polymer film by electrochemical oxida tion under extremely high working potentials are described. A mechanism of polyphenylene formation is suggested. An idea concerning the influence of t he doping and of the solubility of the growing chain on the maximum polyphe nylene molecular weight during the oxidative polycondensation process is pr esented.
