摘　　要：以Fe2+-H2O2为引发体系,合成了丙烯酰胺与淀粉的接枝共聚物.讨论了聚合反应的各个因素对接枝共聚反应的影响,利用高岭土悬浮溶液考察了接枝共聚物的絮凝性能.实验结果表明,接枝聚合物在接枝率为85%时絮凝效果最佳,对高岭土水样的浊度去除率达到80%.Graft copolymers of starch with acrylamide was synthesized using Fe2＋-H2O2 as initiator.The factors of polymerization to graft copolymerization reaction has been discussed and the flocculating property of the copolymer product was determined using aqueous suspension of kaolin.The optimum conditions were that grafted copolymers in grafted rate 85%,the removal rate of turbidity can reach 80%.
