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.
