The Kinetics of polymerization of Acrylonitrile initiated by chloramine-T/H2O2 Redox System was studied in aqueous medium in the temperature range of 35-50 degrees C. The effects of variations such as [Monomer], [CAT], [H2O2], temperature, and chloramine-T disappearance (-R-m) were measured. The effect of some water-miscible organic solvents and surfactants on the rate of polymerization was investigated. The polymerization process is initiated by the free radical arising from oxidation of H2O2 by chloramine-T and terminated by the mutual combination of the growing polymer radicals. Based on the kinetic results, a suitable reaction scheme is proposed and discussed for the various rates of polymerization and thermodynamic parameters were evaluated. (c) 2006 Wiley Periodicals, Inc.
