Abstract
The kinetics of polymerization of acrylonitrile has been studied employing K2S2O8 - EDTA - Ag+ redox couple under atmospheric oxygen. The rate express ion Rp alpha [Monomer](0.45), [K2S2O8](0.42), [Ag+](0.46), [EDTA](0.80) has been obtained and a plausible mechanism suggested to explain the experimen tal findings. The effect of varying concentrations of monomer and redox com ponents, temperature, added salts, solvents, H+ ions and surfactants on the polymerization kinetics have also been studied.
