【Abstract】 Graft polymerization of acrylic acid onto maize starch using ceric ammonium nitrate, ammonium persulfate and ammonium persulfate sodium bisulfate as initiators is studied. Reaction conditions of graft polymerization such as concentration of initiators, reaction temperature, concentration and degree of neutralization of monomer and reaction time are investigated. The results obtained from graft polymerization of acrylic acid onto maize starch initiated with ceric ammonium nitrate, and ammonium persulfate, and ammonium persulfate sodium bisulfate are compared. The best result is that with ammonium persulfate sodium bisulfate.更多还原
