中文摘要：
研究了采用溶液聚合法制备的AA／AMPS共聚物Poly（AA-co-AMPS）水凝胶的吸液性能，结果表明：合成的凝胶材料在0．9％生理盐水中的吸液能力达到125g／g以上；在溶液的pH值5～9时，水凝胶的吸水倍率与最大吸液率的比值（Q／Qmax）最大；水凝胶对NaBr溶液的吸收能力要好于对NaCl溶液的吸收能力；水凝胶对乙醇、氨水溶液的吸收能力随溶液浓度的增高而增大，对尿素水溶液的吸收能力随溶液浓度的增高而减小。
英文摘要：
Poly （AA-co-AMPS） hydrogels were synthesized by the solution polymerization method, and the absorbency of the hydrogels was studied as well. The results showed that the absorbency of the hydrogels was more than 125 g/g in 0.9% NaCl solution, and the value of Q/Qmax was nearly 100 when the pH value was 5-9. The absorbency did not decrease as much as the change of pH value. The absorbency in NaBr solution was higher than in NaCl solution. The absorbency of the hydrogels increased with increasing concentration in ethanol solution or ammonia water, while decreased with increasing concentration in urea solution.
