Kinetics of Polymerization of methylacrylate (MA) initiated by Ce(IV) – Vanillin redox system was carriedout at two different temperatures 30oC & 36oC in dilute sulfuric acid medium under nitrogen atmosphere. The rate ofoxidation of Vanillin by Ce(IV) in the presence and absence of monomer, were studied. The effect of variousconcentrations of [MA], [Ce(IV)], [vanillin], [H+]and varying ionic strengths on the rate of polymerization, rate ofCe(IV) consumption (-Rce) and the percentage monomer conversion were examined. The rate of polymerization in thepresence and absence of β-CD has been investigated The kinetic study of Michelis –menton mechanism for formation ofintermediate complex between reactants allows the oxidation data to be calculated from the plot of Line WeaverBurk.and the activation parameters were computed using Arrhenius and Eyringplots. The rate of polymerization wasalso calculated by iodimetry method. A suitable mechanism has been proposed based on the experimental results.
