摘　　要：研究了以硝酸铈铵、过硫酸铵、过硫酸铵 -亚硫酸氢钠为引发剂玉米淀粉与丙烯酸的接枝共聚反应 .对一些反应条件如引发剂浓度、反应温度、单体浓度、单体中和度、反应时间等进行了考察 ,并比较了以硝酸铈铵、过硫酸铵、过硫酸铵 -亚硫酸氢钠为不同引发体系的淀粉与丙烯酸接枝共聚反应的结果 ,表明用过硫酸铵 -亚硫酸氢钠为引发剂的引发效果最佳 .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.
