反相乳液聚合法合成超高相对分子质量聚丙烯酰胺的研究

Study on synthesis of ultra-high molecular weight polyacrylamide by inverse emulsion polymerization

从引发剂、油水比和加料方式三个不同的角度对合成超高相对分子质量聚丙烯酰胺(PAM)的影响进行了研究.选出最佳的引发剂为过硫酸钾-连二亚硫酸钠,油水质量比为1.1:1,采用分两次滴加27%和35%的丙烯酰胺(AM)的溶液,合成PAM的相对分子质量达16.6×106.

This paper studied the synthesis of ultra-high molecular weight polyacrylamide from initiator system, ratio of oil to water and the way of adding reagents. The optimum initiator system is potassium persulfate-sodium dithionite. The ratio of oil to water is 1.1：1 ,taking two steps to add 27% and 35% of acrylamide to flask, the molecular weight of polyacrylamide is 16.6 ×10^6.
