Synthesis and Structural Characterization of the Self crosslinking Graft Copolymer of Methyl Methacrylate and Butyl Acrylate onto Starch

The characteristics of self crosslinking graft copolymerization of methyl methacrylate(MMA) and butyl acrylate(BA) onto starch were investigated with ceric ammonium nitrate as initiator in the presence of crosslinking agent. The results show that the grafting percentage is higher when the concentrations of initiator and monomer are 8.0×10 -3 and 1.55 mol/L respectively, the temperature of reaction is 58 ℃,and the time of reaction is 2.7 h. The structural characterization of the self crosslinking graft copolymer was determined by IR and X ray diffraction.
