Abstract

Acrylonitrile was polymerized in an aqueous sulphuric acid–methanol medium by an electrolytically generated mediator species, titanium(III). Titanium(III)–dimethylglyoxime was used as the initiator redox system. The reaction was confined to the cathode compartment and was found to proceed via a free radical mechanism. The kinetics of polymerization were investigated for different initial monomer concentrations, acid concentrations, electric currents, dielectric constants of the solvent and electrode materials. A suitable mechanism for titanium(III)– dimethylglyoxime-mediated indirect electropolymerization of acrylonitrile is proposed. Copyright Ó 1999 John Wiley & Sons, Ltd.
