| Abstract: | The graft copolymerization of acrylic acid onto maize starch using ammonium persulfate-sodium bisulfate as initiator was studied in this paper. The factors influencing the rate of graft reaction, such as initiator concentration, monomer concentration, degree of neutralization of monomer, reaction temperature and reaction time were fully investigated. The results showed that the yield, the grafting percentage and the grafting efficiency were raised remarkably by adding materials again. The structure of the copolymer was characterized by IR spectra. |
