Graft copolymerization of vinyl monomers onto natural polymers is a fascinating field of research with unlimited potential application for industrial production of various materials. The natural polymers like gellan gum, dextran, chitosan, guar gum, carboxymethylated guar gum etc. occur abundantly in nature and very useful in pharmaceuticals, food industry, agriculture, cosmetic industry, cosmetics, plastic coating material etc. Though such natural polymers have got tremendous advantages, but it suffers from drawbacks like biodegradatibility, which limits its application. Hence grafting of...
