Kinetics of the polymerization of acrylamide have been studied employing K₂S₂O₈-EDTA-Ag⁺ redox couple under atmospheric oxygen. The rate expression has been obtained and a plausible mechanism suggested. The effects of varying concentrations of monomer, redox components, temperature, added salts, H⁺ ions and surfactants on the polymerization kinetics have been studied.
