摘　　要：以丙烯酰胺(AM)、丙烯酸(AA)和对苯乙烯磺酸钠(SSS)为单体,过硫酸钾为引发剂,N,N'-亚甲基双丙烯酰胺为交联剂,采用溶液聚合法制备出AM-AA-SSS三元共聚物。结果表明,聚合最佳条件为:AA用量10 mL,AM用量3.3 g,SSS用量0.5 g,引发剂用量0.040 g,交联剂用量0.010 g,反应温度60℃。在此条件下,试样的吸蒸馏水倍率为259 g/g,吸盐水倍率为42 g/g。Acrylamide(AM)-acrylic acid(AA)-sodium p-styrene sulfonate(SSS) terpolymer was synthesized by solution polymerization with AM,AA and SSS as monomers,potassium persulfate as initiator,N,N′-methylene bisacrylamide as crosslinking agent.The results showed that the optimum synthetic conditions were AA 10mL,AM 3.3g,SSS 0.5g,initiator 0.040g,crosslinking agent 0.010g,reaction temperature 60℃.Under these conditions,the water absorption rate of the polymer was 259g/g,the salt water absorption rate of the polymer was 42g/g.
