Abstract

The kinetics of cyclopolymerization of N,N’-methylenebisacrylamide (MBA) was carried out using a novel chargetransfer complexes of N,N-dimethylaniline(DMA)-Benzoyl chloride (BoCl) and N,N-dimethylaniline-Trichloroacetic acid (TCA). The reactions were carried out under various conditions of concentrations at constant temperature of 52ºC in aqueous medium. The dependence of rate of polymerization on various experimental conditions such as different concentrations of monomer MBA, donor DMA and acceptors BoCl and TCA were studied. The order with respect to monomer, donor and acceptors was found to be 1, 0.5 and 0.5 respectively. The kinetic results were interpreted by a suitable mechanic sequence. Absence of gelation is attributed to the formation of a cyclic polymer. Jobs method of continuous variation studies show that 1:1 complex formation.
