| 摘 要： | 以AMPS和丙烯酸（AA）为原料，N，N-亚甲基双丙烯酰胺为交联剂，采用静置水溶液聚合法合成了耐盐性能较好的高吸水性树脂。经正交实验研究了合成反应的工艺条件，在n(AA)/n(AMPS)为85/15，交联剂质量分数为0.0125%，引发剂质量分数为0.05%，中和度为90%，单体质量分数为35%，反应温度55～75℃。合成树脂的吸水率大于900 g/g，在0.9%的生理盐水中吸液能力达到125 g/g以上，在1.8%盐水中的吸液能力依然超过100 g/g。

| Abstract: | With AA and AMPS as main raw materials，NMBA as crosslinking agent，a super absorbent of high salt tolerance was synthesized in aqueous solution. The mol ratio of AA/AMPS was 85/15，the mass of cross–linking agent was 0.0125%，and the mass of initiatoris was 0.05%. AA was neutralized partially by 90% sodium hydroxide，the mass of monomer was 35% in solution，and reaction temperature was 55～75℃. The results showed that super absorbent synthesized could absorb water as high as 900 g/g，125 g/g in 0.9% NaCl solution and 100 g/g in 1.8% NaCl solution. |
