The polymerization kinetic of methacrylamide with the KMnO4/glycine redox system has been investigated volumetrically at 35 +/- 0.1degreesC under nitrogen atmosphere in aqueous sulfuric acid medium in a dimethylsulfoxide/H2O mixture (5% v/v). The rates of polymerization were found to obey the following equation: R-p proportional to [Methacrylamide](1.08)[Glycine](0.44)[KMnO4-](0.46). A glycine end group containing polymethacrylamide was prepared by the MnO4-/glycine redox system under mild conditions. The reaction proceeded with radical mechanism and the overall energy of activation (E-a) was calculated to be 29.87 kj/mol from the Arrhenius plot in the temperature range 25-50degreesC. Molecular weight of the polymer was determined by viscometry. (C) 2003 Wiley Periodicals, Inc.
