摘要

采用预辐照的方法研究了淀粉与丙烯酰胺的接枝反应，制备出了淀粉与丙烯酰胺的接枝物；采用元素分析法测量了接枝率。对预辐照接枝反应的一些影响因素，如吸收剂量、反应温度、反应时间、阻聚剂及辐照后效应也进行了研究，并获得了相关结果。淀粉预辐照的吸收剂量约10kGy，辐照后10min内在25～30℃下进行接枝可以获得80%以上的接枝率。

Abstract

In present paper, the grafting reaction of starch-acrylamide by ,60,Co γ pre-irradiation was carried out. The grafted copolymer was prepared and identified by IR spectrophotometer. The grafting yield was measured with element analysis. Various influence factors such as absorbed dose, reaction temperature, reaction duration, post-irradiation effect etc. on grafting yield were studied. The grafting yield higher than 80% could be obtained when the grafting reaction was proceeded at 25~30℃ within 10minutes after 10kGy irradiation.
