Synthesis of chitosan-grafted-poly (Methyl Methacrylate) with fenton's reagent (FE2+ - H2O2) as a redox initiator
Graft copolymerization of poly(methyl methacrylate)(PMMA) onto chitosan fiber has been successfully carried out using Fenton’s Reagent which is consisted of hydrogen peroxide(H2O2 ) as initiator and ferrous ammonium sulphate(FAS) as cocatalyst under inert atmosphere in an aqueous medium. The PMMA ho...
