摘　　要：对丙烯酰胺(AM)改性阳离子淀粉的工艺条件进行了探索,结果表明最佳条件为:反应温度50℃,反应时间8.0h,阳离子淀粉取代度0.026,AM用量4%。试验证明AM在阳离子淀粉非糊化的条件下也能进行接枝共聚,得到改性阳离子淀粉样品,样品在造纸上应用,应用效果良好。The technological conditions of modified cationic starch with acrylamide had been explored.The results showed that the best conditions were as followed ： reaction temperature 50℃,reaction time 8.0h,the substitute degree of cationic starch 0.026,3% mass fraction of acrylamide.The experiments proved that AM could be carried out the graft copolymerization with cationic starch under the condition of non-gelatinization,and samples of modified cationic starch were obtained.The samples were applied to papermaking and the effect was good.
