摘要
以淀粉与丙烯酰胺 (AM)为原料 ,采用UV聚合法制备淀粉与丙烯酰胺接枝共聚物 (St-PAM)。通过实验得出较佳的工艺条件为 :淀粉糊化温度为 90℃ ;糊化时间为 1h ;AM与淀粉的最佳配比为 1:1 6 (质量比 ) ;引发剂用量是 1 2g/L ,交联剂用量 3g/L ,在此条件下得到的接枝共聚物接枝率和接枝效率最高。用IR对产物的结构进行了表征 。
Making use of UV polymerization produces starch and acrylamide graft-copolymer with starch and acrylamide served as raw materials. Optimization conditions are achieved by experiments:the temperature that starch melts paste is 90℃; paste melt time is an hour; the best mix ratio of the AM and starch is 1:1.6 (by mass); initiator does is 1.2g/L; crosslinking agent does is 3 g/L; the graft ratio and efficiency are the highest under the conditions; the production structure has been characterized by IR;the flocculation of the graftcopolymerizatio production has been studied also.
