We have studied the polymerization kinetics of acrylamide in aqueous solution with potassium persulfate as ail initiator by using quantitative real-time in situ IR spectroscopy and monitoring the profiles of peaks in the range 1900-850 cm(-1). The conversion of acrylamide was calculated from the disappearance of the peak at 988 cm(-1), which is the out-of-plane bending mode of the = C-H unit, normalized to the C=O stretching peak at 1675 cm(-1) as an internal standard. For reaction temperatures in the range 40-65 degreesC and initiator and monomer concentrations of 0.9-2.6 mmol/L and 0.5-1.1 mol/L, respectively, we deduced that the rate of monomer consumption follows the relation R-P = k[ K2S2O8\(0.5)[M](1.35+/-0.10). In addition, we obtained activation parameters from ail evaluation of the kinetic data.
