Electroinitiated polymerization of bis(4-bromo-2,6-dichlorophenoxo)N,N,N′,N′-tetramethylethylenediamine copper(II) complex was achieved upon oxidation. Prior to polymerization a cyclic voltammogram (CV) of the complex was obtained. Polymerization potentials were selected as the oxidation and reduction peak potentials of the complex, obtained by CV. Polymers in the form of poly(dihalophenylene oxide), were obtained by constant potential electrolyses carried out at redox peak potentials of the complex. No ligand or copper was found to incorporate into the final polymer product. The mechanism of polymerization was found to be free radicalic. It was also found that post-polymerization proceeds in the absence of current, when current is ceased after approximately 10 minutes of electrolysis. Percent conversions of polymerization had been measured by an electrochemical technique via simultaneous measurement of reacted monomer concentration. In order to follow the reacted monomer concentration by simultaneous CV measurement, a special H-type electrolysis cell with six electrodes was constructed. Polymers were characterized by 1H-n.m.r., 13C-n.m.r. and FTi.r. spectroscopy along with molecular weight measurements by the isopiestic method.
