- Polymer Research Laboratory, Department of Chemistry, Rani Durgavati Vishwavidyalaya, Jabalpur-482 001 Manuscript received 4 October 1991, revised 9 June 1992, accepted 21 September 1992 Kinetics of aqueous polymerization of acrylamide with KMnO4/sodium metabisulphite redox pair were studied at 35° under atmospheric oxygen. The rate of polymerization was found dependent on first power of the monomer and catalyst while half power of the activator concentration. The energy of activation has been found to be 10.5 kcal mol-1 between 25 and 45°. The effect of various additives on the course of polymerization was studied qualitatively. The retarding effect of organic solvents has been studied quantitatively and retardation constants have been calculated using newly developed 'Intercept method'.
