SYNTHESIS OF MAINLY LINEAR POLY(DICHLOROPHENYLENE OXIDE) BASED ON THEELECTROOXIDATION OF YRIDINE)BIS(4-BROMO-2,6-DICHLOROPHENOXO)COPPER(II) COMPLEX IN DIMETHYLFORMAMIDE

Anodic oxidation of yridine)bis(4-bromo-2,6-dichlorophenoxo)copper(II) complex leads mainly to linear poly(2,6-dichlorophenylene oxide) unde r constant-potential electrolysis in the dimethylformamide-tetrabutyla mmonium tetrafluoroborate solvent-electrolyte couple at room temperatu re under air or nitrogen. Polymerization conditions were based on the peak potentials measured by cyclic voltammetry. Characterization of th e polymer was performed by C-13 and H-1 nuclear magnetic resonance, Fo urier-transform infra-red spectroscopy, differential scanning calorime try, molecular-weight and dipole moment measurements.
