摘　　要：采用60Coγ射线共辐照的方法制备出了淀粉与丙烯酰胺的接枝共聚物,并计算接枝率。研究了吸收剂量、反应温度、淀粉与丙烯酰胺配比对接枝反应的影响,获得了相关结果。淀粉与丙烯酰胺共辐照剂量约10kGy,反应温度30℃,丙烯酰胺与淀粉配比2:1的条件下可以获得较高的接枝率。The graft copolymerization of corn starch with acrylamide was prepared by ^60Coγ-ray mutual radiation, and the grafting yield was studied.The effect of absorbed dose, reaction temperature, mass ratio of acrylamide and starch on grafting yield were studied. The results showed when absorbed dose was 10kGy, reaction temperature was 30℃, m （acrylamide） ：m （starch） = 2： 1, the prod uct had high grafting yield.
