Polymer Modifications (Grafting): Approach to Enhance Versatility of Natural/Renewable Polymeric Materials
Abstract: Graft copolymers are branched copolymers containing a long chain of one monomer called preformed or backbone polymer and branches/grafts of long sequences of usually another monomer. A number of monomeric units can be grafted on the biopolymeric backbone by free radical graft copolymerization reaction using chemical free radical initiator to produce reactive sites on the backbone of biopolymer. The chemical combination of natural and synthetic polymers yields new materials which …
