采用反相悬浮聚合法,通过均匀实验设计,制备了聚(丙烯酸(AA)/2-丙烯酰胺基-2-甲基丙磺酸(AMPs))(PAAMPS)高吸水树脂,探讨了单体摩尔分数及其中和度、引发剂及交联剂摩尔分数(相对于单体总量)对蒸馏水、质量分数0.9％ NaCl水溶液中吸液性能的影响,并经实验数据拟合,得到了二次回归方程,比较了优化配方、单因素实验的模拟值和实验值,结果表明,模拟值与优化值基本接近,其优化工艺参数为:AMPS占单体的摩尔分数8％,中和度为75％,交联剂、引发剂用量与单体的摩尔分数分别为0.035％和0.17％,单体总质量浓度为30％,分散剂用量为单体质量分数的0.5％,反应温度70℃,反应时间1.5h.此条件下合成的PAAMPS在蒸馏水、0.9％ NaCl水溶液中的吸液倍率分别为1600和130 g/g.
