1. Title : Graft Copolymerization of MMA onto cellulose
2. Date :
3. Principle :
Graft Polymer : A polymer comprising molecules in which the main backbone chain of atoms has attached to it at various points side chains containing different atoms or groups from those in the main chain. The main chain may be a copolymer or may be derived from a single monomer. Therefore, when chains of a polymer made of monomer B are grafted onto a polymer chain of monomer A we gave a graft copolymer
Grafting may be used to enhance the physical properties of the material composing the main chains. Because the physical and chemical properties of the grafted polymer are different depending on the molecular weight of the main chains, number and monomer, be need to understand the characteristics of the reaction mechanism of grafting. This can be obtained by measuring the weight conversion(WC; %) of the grafted monomer, grafting percentage(GP; %) of the grafted monomer, grafting percentage(GP; %), and the grafting efficiency(GE; %)
WC(%)=C/B×100
=(total weight of PMMA formed)/(weight of MMA charged)×100
GP(%)=D/A×100
=(weight of graft PMMA)/(weight of cellulose)×100
GE(%)=D/C×100
=(weight of graft PMMA)/(total weight of PMMA formed)×100
