摘　　要：研究了淀粉与丙烯酰胺辐照接枝共聚的反应条件。以单因素实验考察了淀粉与丙烯酰胺质量比、淀粉乳浓度和辐照剂量3个因素对接枝率的影响。通过正交实验确定了最佳反应条件为:淀粉与丙烯酰胺质量比1:2,淀粉乳浓度6%,辐照剂量10kGy。通过高岭土悬浊液絮凝实验结果表明:高岭土悬浊液的浊度去除率可达到86.33%。This study has been researched on the reaction condition of corn starch and acrylamide been grafted copolymerization by way of irradiation.Grafting yield was under the influence of matching ratio of starch and acrylamide,concentration of starch milk and metering of irradiation in the single factors＇ experiment.The best optimized reaction condition were given by the orthogonal test：matching ratio of starch and acrylamide is 1：2,concentration of starch milk is 6%,metering of irradiation is 10 kGy.The rate of removal on turbidity can reach as 86.33% through the test of kaolin soliquoid.
