Radical polymerization of methyl methacrylate complexed with β-cyclodextrin in homogeneous aqueous medium

The radical polymerization of)g-cyclodextrin host-guest complexes of methyl methacrylate initiated by Potassium Peroxydisulphate in homogeneous aqueous solution have been studied. The effect of change of monomer and initiator concentration, temperature, time and different solvents on the rate of polymerization are studied. The rate of polymerization of uncomplexed methyl methacrylate are also studied. It is observed that, the polymerization occurred much faster and the percentage of conversion of monomer and the rate of polymerization are more in case of polymerization of complexed MMA in comparison to uncomplexed monomer. The rate of polymerization in presence of organic solvents are also studied. The viscosity and the molecular weight of polymer obtained in presence of beta-cyclodextrin is found to be higher in comparison to the polymer obtained in absence of P-cyclodextrin.
