| Abstract: | In this paper, graft polymerization of acrylic acid onto maize starch using ammonium persulfate-sodium bisulfate as initiator is studied. The important reaction conditions of graft polymerization are investigated. The result shows that the yield, the graft yield and the graft efficiency are 64.04%, 73.82%, and 86.43%, respectively. The mechanism of initiation is also discussed. |
