摘要
以丙烯酰胺 (Am)和淀粉 (St)为原料 ,以硝酸铈铵为引发剂 ,在通氮气保护下进行接枝共聚反应 ,得到淀粉丙烯酰胺阳离子接枝共聚物 (简称 SAM) ,聚合中加入一定量的阳离子单体二甲基二烯丙基氯化铵制得另一接枝共聚物 (简称 C- SAM)。研究表明当SAM的单体 [St]与 [Am]的质量比为 1∶ 3,C- SAM中的 [St]与 [Am]的质量比为 1∶ 4 ,阳离子单体二甲基二烯丙基氯化铵为 10 % (以 Am的质量分数计 )
It was discussed that synthesis, properties and application of copolymer (SAM, C-SAM) of acrylamide (Am) and starch (St). The results show that the copolymer obtained when the ratio of St and Am was 1∶3 (wt), or ratio of AM, St and DADMAC was 1∶4∶0.4 (wt), have high effect of flocculation. When the copolymer was used for white water of papermaking, it has a remarkable effect on flocculation.
