Abstract

Kinetics of Polymerization of methylacrylate (MA) initiated by Ce(IV) – Vanillin redox system was carried
out at two different temperatures 30oC & 36
oC in dilute sulfuric acid medium under nitrogen atmosphere. The rate of
oxidation of Vanillin by Ce(IV) in the presence and absence of monomer, were studied. The effect of various
concentrations of [MA], [Ce(IV)], [vanillin], [H+
]and varying ionic strengths on the rate of polymerization, rate of
Ce(IV) consumption (-Rce) and the percentage monomer conversion were examined. The rate of polymerization in the
presence and absence of β-CD has been investigated The kinetic study of Michelis –menton mechanism for formation of
intermediate 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 was
also calculated by iodimetry method. A suitable mechanism has been proposed based on the experimental results.
