Özet

Polymerization of bis(2-bromo-4,6-dichlorophenoxo)bis(pyridine) copper (II) complex was achieved in dimethylformamide by electrooxidation. A cyclic voltammogram (CV) of the complex was obtained in dimethylformamide in advance. Constant potential yielded polymers in anode compartment only under nitrogen atmosphere and air. In the final polymer product, incorporation of neither the ligand nor the copper was observed and the post-polymerization proceeded in the absence of current. The structural analyses of the polymers were done by C-13 n.m.r., H-1 n.m.r., FT1.r. spectroscopy, differential scanning calorimetry (d.s.c.) and dipole moment measurements. The molecular weight of the polymer was determined by cryoscopic method. The poly(dihalophenylene oxides) obtained at different potentials were found to be similar in structure and both 1,2 and 1,4 catenations took place at roughly equal rates.
