| 摘 要： | 以无机盐水溶液为介质的分散聚合是一种绿色合成法。为缩短分散聚合的工艺过程和提高线型阳离子聚丙烯酰胺的絮凝效果,采用了两段加料法合成阳离子聚丙烯酰胺分散体,并在聚合过程中加入乙烯基异丁醚对阳离子聚丙烯酰胺进行改性。用傅立叶红外光谱对改性前后产物的结构进行分析,然后将阳离子度相近的两种产物应用于高岭土悬浊液的絮凝。通过对比上清液浊度、分维数和压缩屈服应力等参数,发现用乙烯基异丁醚对阳离子聚丙烯酰胺进行改性能提高其絮凝性能。

| Abstract: | Dispersion polymerization in inorganic salts solution is a kind of green polymerizations. In order to shorten the process engineering of dispersion polymerization and enhance the flocculation performance of linear cationic polyacrylamide,the two-stage feeding method was employed to synthesize cationic polyacrylamide dispersions,and the modified cationic polyacrylamide was synthesized by adding the vinyl isobutyl ether to copolymerize. The structures of cationic polyacrylamide and modified cationic polyacryl... |
