The decomposition of bis-(2,4,6-tribromophenoxo) ethylenediamine copper(II) complex in dimethylformamide by electro-oxidation yields low molecular weight (4.5 × 103) linear poly(dibromophenylene oxide). Electro-initiated polymerization was accomplished upon oxidation by a constant potential electrolysis under air or under N2 at room temperature. Polymerization conditions were based on the peak potentials measured by cyclic voltammetry. Constant peak potentials carried out at anodic and cathodic peak potentials yielded polymers in the anolyte only. The kinetics of the polymerization were followed by obtaining the unreacted monomer concentration by in situ cyclic voltammetry measurements during electrolysis. The characterization of the polymer was performed by 1H-NMR, 13C-NMR and FTIR spectroscopies. For determination of , the isopiestic method was used.
