Grafting of methyl acrylate onto sodium salt of partially carboxymethylated guar gum (backbone) was carried out using ceric ammonium nitrate as a redox initiator in an aqueous medium. The reaction variables including concentrations of initiator, nitric acid, monomer and amount of the backbone as well as time and temperature were varied for establishing the optimized reaction conditions for grafting. The influence of these reaction parameters on the grafting yields and the rates of polymerization, graft copolymerization and homopolymerization was also studied and the results were discussed. The kinetic scheme of free radical graft copolymerization was proposed and the experimental results were found to agree very well with the proposed kinetic scheme. The graft copolymer sample was characterized by IR-spectroscopic, thermal and scanning electron microscopic techniques.

Introduction: Graft copolymerization is one of the most promising technique uses to modify the properties of naturally available polymers with a minimum loss in their native characteristics. Methods and Materials: Graft copolymerization is a very significant technique to add hybrid properties in backbone of polymers. The grafting generally initiated through the formation of free radical centers on the polymer backbone as well as monomer. Results: Grafted polysaccharides have various applications in different important scientific areas such as drug delivery, pharmaceutical field, plastic industry, waste water treatment, tannery effluent treatment, textile industry, agriculture area, etc. all of this fascinated us to summarize the major research articles over the last two decades outlining different methods of grafting, surface modification, graft copolymerization of synthetic and natural polymers. Conclusion: Various redox initiator systems viz. Ceric ammonium nitrate, per sulfate, Irradiation, FAS-H2O2 etc. is also explored for grafting of vinyl through conventional and non-conventional techniques.
