The electroinitiated polymerization of styrene in tetrabutylammonium perchlorate-dimethylsulphate solutions has been investigated. Polystyrene of low molecular weight is formed cationically through a direct monomer oxidation to the radical cation. Kinetic as well as mechanistic considerations for th
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
