- Department of Chemistry, University of Jammu, Jammu-180 001 The homogeneous polymerization of methacrylamide (M) was studied in aqueous sulphuric acid medium at 35±0.2° under a nitrogen atmosphere. The rate of monomer disappearance was proportional to [MA]1[Ce(IV)1[M]1.2 and the rate of ceric ion disappearance was directly proportional to [Ce(IV)] but independent of [Mb The rate increased very slowly upto a certain range of malic acid (MA) concentration above which it remained constant. A very stable complex was revealed by Lineweaver-Burk plot of rate-1 vs [MA]-1. Increasing reaction temperature increased the rate from 25 to 45°. The activation energy was found to be 15.25 k cal mol-1. By decreasing \(p\)H of the medium the rate of polymerization decreased.
