✦ Synopsis

The electrochemical polymerization of cyclohexylvinylether has been investigated in 1,2dichloroethane solution using various tetrabutylammonium salts, viz. tri-iodide, iodide, tetrafluoroborate and perchlorate, as supporting electrolytes in reaction ceils with two platinum electrodes. The first two salts were unsuitable for an electrochemical polymerization: in the presence of tetrafluoroborate or perchlorate, pulses of constant current induce an anodic polymerization for which the electrochemical and kinetic characteristics have been examined. Initiation is attributed to electrochemically formed protons but their source seems different from that generally reported. Anodic polarography and potentiostatic electrolyses of the electrolyte solutions have excluded the oxidation both of the solvent and the supporting salt, besides that of the monomer. Hence. it is likely that the initiating protons arise from the electrochemical oxidation of residual water.
