中文摘要：
以AMPS和丙烯酸（AA）为原料，N，M-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）In（AMPS）为85／15，交联荆质量分数为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＂C。合成树脂的吸水率大于900g/g，在0．9％的生理盐水中吸液能力达到125g／g以上，在1．8％盐水中的吸液能力依然超过100g/g。
英文摘要：
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 inifiatoris 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.
