以木质素磺酸钠（LS-Na）、2-丙烯酰胺基-2-甲基丙磺酸（AMPS）、丙烯酸（AA）为原料，N，N-亚甲基双丙烯酰胺为交联剂，过硫酸钾为引发剂，采用微波辐射法，通过接枝共聚合成了具有生物降解性能的LS-g-PAMPS/AA高吸水性树脂。探讨了单体配比、LS-Na用量和单体总用量对LS-g-PAMPS/AA树脂吸水倍率的影响，研究了该树脂在各种盐溶液中的溶胀行为，并利用FTIR和TG等方法分析了该树脂的结构。实验结果表明，当m（AA）∶m（AMPS）=3、LS-Na用量（基于体系总质量，下同）为6%（w）和单体总用量为35%（w）时，LS-g-PAMPS/AA树脂在去离子水和生理盐水中的吸水倍率分别为1217 g/g和125 g/g。LS-g-PAMPS/AA树脂具有较强的热稳定性、耐盐性和盐响应性能，在不同的盐溶液里有良好的可逆行为和多次反复利用性能。

Novel biodegradable LS-g-PAMPS/AA superabsorbent resins were synthesized from lignosulfonate(LS-Na),2-acrylamido-2-methyl propanesulfonicacid(AMPS) and acrylic acid(AA) by grafting copolymerization under microwave irradiation with potassium persulfate as initiator and N,N-methylene-bis-acrylamide as crosslinking agent. The effects of mass ratio of AA to AMPS,LS-Na dosage and total monomer amount on the water absorbencies of the superabsorbent resins were studied. The swelling behaviors of the superabsorbent resins in various salt solutions were investigated. The microstructures of the superabsorbent resins were characterized by means of FTIR and TG. The results showed that under the reaction conditions ofm(AA)∶m(AMPS) of 3,LS-Na dosage of 6%(w) and total amount of AMPS,AA and LS-Na of 35%(w),the water absorbency of the superabsorbent resin was 1 217 g/g in deionized water and 125 g/g in normal saline. The superabsorbent resin showed excellent thermal stability,salt tolerance and salt response,and the resin exhibited good reversible swelling behavior and reusability in the salt solutions.
