Summary The polymerization of acrylamide initiated by Ce 44+/L-cysteine redox system has been studied at 35 ± 0.2 °C in dark under nitrogen atmosphere. The effect of monomer,L-cysteine, Ce4+ and sulphuric acid concentration and temperature on the rate of polymerization has been studied. The rate may be expressed by the following equation:R p α[M] [Ce4+]0.5 [Cysteine]0.44 The overall energy of activation is 4.78 kcal/deg/mole in the investigated range of temperature 30–50 °C. Molecular weight of the polymer is independent of catalyst concentration but increases with increasing monomer concentration.
