✦ Synopsis

Almtraet--Bis(4-bromo-2,6-dichlorophenoxo) ethylenediamine copper(lI) complex has been polymerized using electro-initiation by constant potential electrolysis, in dimethylformamide--tetrabutylammonium fluoroborate solvent-supporting electrolyte couple, at room temperature under air or N2. The process leads to low molecular weight (5.6 x 103) linear poly(dichlorophenylene oxide). The structures of the polymers were determined by I H-NMR and ~3C-NMR. The kinetics of the polymerization were followed by /n situ cyclic voltammetry measurements during electrolysis. Unlike thermal polymerization of this complex, the polymerization by electro-initiation begins immediately.
