Polymerization of non-conjugated divinyl monomer N,N'-methylenebisacrylamide was studied using a novel charge-transfer complex of N,N-dimethylaniline-benzenesulphonyl chloride in a homogeneous gel-free state, under varying conditions of concentration and temperature. The reactions were carried out under various concentrations at a constant temperature of 52 ? in acetonitrile media. The dependence of the rate of polymerization on various experimental conditions, such as different concentrations of monomer N,N'-methylenebisacrylamide, donor N,N-dimethylaniline, acceptor benzenesulphonyl chloride, and temperature were studied. The order with respect to monomer, donor, and acceptor were found to be 1, 0.5, and 0.5 respectively. The kinetic results were interpreted by a suitable mechanistic sequence. Absence of gelation is attributed to the formation of a cyclic polymer. Jobs method of continuous variation studies shows 1:1 complexformation.
