The kinetics of methyl acrylate (MA) polymerization initiated by a V(V)‐Cyclohexanone redox system, in the presence of surfactant, over a temperature range of 30–50°C in acidic medium are analyzed. The anionic surfactant (SDS) enhances the rate of polymerization ( R p ) as well as the rate of V(V) consumption (− R v ). The cationic surfactant, cetyl trimethylammonium bromide (CTAB), decreases both the rates. The effect of variation of the concentration of surfactant, monomer, substrate, and acid have been examined. A suitable free radical mechanistic scheme has been proposed for the above process. © 1997 John Wiley & Sons, Inc. J Appl Polym Sci 66: 2081–2088, 1997
