Polymerization of n, nʹmethylene bis acrylamide initiated by ce(iv) – vanillin redox system in the absence and presence of β-cyclodextrin

Kinetics of Polymerization of N,NʹMethyleneBisacrylamide (MBA) initiated by Ce(IV) – Vanillin redox system, was carried out two different temperatures 30oC & 36oC in dilute sulfuric acid medium under nitrogen atmosphere. The rate of oxidation of Vanillin by Ce (IV) in the presence and absence of β-CD were studied. The effect of various concentrations of monomer [MBA], oxidant [Ce(IV)], reductant[van], medium[H+] and varying ionic strengths NaHSO4 on the rate of polymerization, rate of Ce(IV), consumption (-RCe) and the percentage monomer conversion were studied. The rate of polymerization (Rp)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 Weaver-Burk. The rate of polymerization(Rp) was also calculated by iodometry method. On the basis of experimental results a suitable mechanism has been proposed.
