| 摘 要： | 以丙烯酸和2-丙烯酰胺基-2-甲基丙磺(AMPS)为单体，采用溶液聚合法合成了聚(丙烯酸盐-co-2-丙烯酰胺基-2-甲基丙磺酸盐)高吸水性树脂。考察了交联剂、引发剂用量，AMPS与丙烯酸摩尔比，AMPS水溶液浓度，丙烯酸和AMPS中和度，反应温度等因素对吸水树脂吸水性能的影响。制得的吸水性树脂30min吸蒸馏水和0．9％NaCl水溶液分别为1350g／g和150g／g，且凝胶强度较好。

| Abstract: | A superabsorbent resistant to saline solution was prepared from copolymer of acrylic acid with 2-acrylamide-2-methyl propyl sulfonic acid (AMPS) by solution polymerzation. The effects of the amount of crosslinker and initiator, mole ratio of AMPS to acrylic acid (AA) , degree of neutralization of AA and AMPS, concentration of AMPS ,temperature of reaction on water absorbency (WA) and the hydrogel modulus were investigated. The results show that WA of the superabsorbent is about 1350 and 150 in distilled water and 0.9%NaCl solution for 30 min. The superabsorbent also has an excellent hydrogel modulus. |
