Abstract
The aqueous polymerization of acrylamide initiated by the potassium persulfate/lactic acid system catalyzed by Ag+ ions has been studied iodometrically over the temperature range from 35 to 50 ± 0.2°C. The rate of polymerization is governed by the expression Rp ∞ [M]0.8[K2S2O8]1.0[Ag]1.0 The deviation from normal kinetics has been studied. A tentative mechanism of initiation is suggested. The overall energy of activation is 5.52 kcal/mol.
