Abstract
The electroinitiated copolymerization of styrene and commercial divinylbenzene has been carried out in an intimately mixed two phase system made of a polar phase consisting of a highly polar solvent, i.e., formamide together with ferric chloride as the added electrolyte, and a non-polar phase formed by the mixture of the two monomers themselves or their solutions in a non-polar solvent like benzene or toluene. The copolymer formed was found to be partially crosslinked and its formation depended on several factors such as the intensity of stirring, concentrations of the electrolyte and the comonomers, strength of the current flow, time of electrolysis and temperature. In split cell experiments, the copolymer is found to be formed in the cathode compartment. A radical mechanism has been proposed to explain the copolymerization reaction.
