摘　　要：采用反向悬浮聚合法制备了丙烯酸 (钠 )与丙烯酰胺共聚物 ,通过分散剂的选择 ,得出了以羧甲基纤维素、Span- 80、羊毛脂为分散剂的较稳定的聚合体系 ,其产物呈颗粒状 ;探讨了聚合反应条件的影响 ,并测试了共聚物的部分性能。Acrylic acid and its sodium salt and acrylamide copolymer (PAA-PAA Na-PAM) were prepared by inverse suspension polymerization . In the polymerizing water soluble monomers were reaction system , polymerized by using potassium persulfate as initiator, cyclo-hexane as the continuous phase , N,N ′- methylenebisacylamide as the cross-linking agent, and CMC, Span-80,Wool Fat as the disperser. The effects of the disperser, degree of neutralization of AA, crosslinking agent used on the copolymer, properties of the copolymer were also studied.
