摘　　要：以玉米淀粉和丙烯酰胺为原料,过硫酸铵为引发剂,用水溶液聚合法合成了淀粉接枝丙烯酰胺絮凝剂。研究了反应温度、反应时间和引发剂用量等反应条件对单体转化率、接枝率、接枝效率、絮凝性能的影响。结果表明:在淀粉与丙烯酰胺单体的质量比为1∶2,反应温度为45℃,反应时间为3h,引发剂用量为单体的1.25%时,产物接枝效率、单体转化率、接枝率最高,絮凝性能较优。Flocculant was synthesized from corn starch and acrylamide by aqueous solution polymerization using ammonium persulfate as the initiator. Result showed that when the temperature is 45 ℃, the quality ratio of starch to acrylamide is 1 ： 2 and initiator amount is 1.25% of the monomer , the product grafted highest , and also the best performance of the flocculant was also found rate, monomer conversion and under the condition above. grafting efficiency are
