AbstractPolymerization of methyl methacrylate (MMA) using Ce(IV) as initiator in aqueous nitric acid solution in the presence of sodium lauryl sulphate (NaLS) has been studied kinetically at a temperature range of 25–35°C. The rate of polymerization (Rp) increases with increasing concentration of NaLS, and it was also proportional to MMA2; but, in the presence of NaLS, the change ofRpwith respect to Ce(IV) and H+ were not linear and similarly the rate of Ce(IV) disappearance was not proportional to its original concentration. The overall activation energy of the polymerization process in presence of 0.01MNaLS was found to decrease by ∼ 7.0 kcal mol−1. The monomer–micelle association constant has been calculated to be 5.135 × 104mol−1L. The polymer obtained in surfactant medium is sparingly soluble in benzene and DMSO. From infrared spectra clear evidence of vinyl polymerization w
