摘要
以APS为引发剂,研究了丙烯酰胺与烯丙基磺酸钠的水溶液共聚合反应,考察了单体配比、反应温度、APS浓度等对共聚反应的影响。用IR、1H-NMR和[η]对共聚物进行了表征,并用1H-NMR谱测定了共聚物的组成,计算出了30℃时共聚单体的竞聚率。
The copolymerization of acrylamide with sodium allylsulfonate in aqueous solution using ammonium persulfate as the initiator was studied.The copolymers were characterized by IR and ̄1HNMR spectroscopies. And the reactivity ratios(r1=2. 67,r2=0. 31, 30.0℃) were calculated by Kelen-Tudos method and Finoman-Ross method. The flocculation of Kaolin suspension contained salt with the copolymers was also studied.
