Redox behaviour of 4-allyl-1,2-dimethoxybenzene (DMAB) was studied by using cyclic voltammetry and electro-chemical polymerization was conducted at the measured peak potential. Constant potential electrolysis of the monomer was carried out in acetonitrile-tetrabutylammonium-tetrafluoroborate, solvent-electrolyte couple, at room temperature. Electrochemical polymerization of the monomer yielded insoluble polymer film on the electrode surface together with the low molecular weight polymers in bulk of the solution. The effect of temperature on the rate of electro-chemical polymerization was also studied. The structural analyses of the polymers were done by H-1-NMR and FTIR spectroscopy. Molecular weight of the soluble polymer was determined by cryoscopy. (C) 2004 Elsevier B.V. All rights reserved.
