- Department of Physical Chemistry, Indian Association for the Cultivation of Science, Jadavpur, Calcutta.-32 Manuscript received 16 November 1972; revised 27 June 1973; accepted 7 November 1973 Conversion-time data were obtained for the polymerization of acrylamide in water initiated by hydrogen peroxide hydroxylamine redox pair. The polymerization was carried out under nitrogen at 30°; the yield was obtained gravimetrically, using an excess of methanol-acetone mixture as precipitant. The effect of initiator concentration, monomer concentration and temperature have been studied. The overall activation energy between 30°-50° is about 6.5 Kcal/mole, It appears from the dependence of the rate of polymerization on the initiator concentration and end group analysis that a free radical mechanism is operative here.
