The Kinetics of polymerization of Acrylonitrile initiated by chloramine‐T/H 2 O 2 Redox System was studied in aqueous medium in the temperature range of 35–50°C. The effects of variations such as [Monomer], [CAT], [H 2 O 2 ], 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 H 2 O 2 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. © 2006 Wiley Periodicals, Inc.
