摘　　要：对丙烯酸(AA)、丙烯酰胺(AM)的水溶液聚合反应进行了研究,合成了高吸水性树脂,探讨了中和度、单体配比、交联剂用量、引发剂用量、水浴温度等对高吸水性树脂吸液倍率的影响,并用红外光谱对产物的结构进行了表征。5min合成的高吸水性树脂吸水倍率高达1600g.g-1,在质量分数为0.9%的食盐水中的吸液倍率达155g.g-1。The aqueous solution polymerization of acrylic acid and acrylamide was studied, and a super absorbent resin was synthesized. The factors that influence on liquid absorbency rate of the super absorbent resin were discussed, including neutralization degree of AA, monomer ratio, crosslinking agent dosage, initiator dosage and water bath temperature. The structure of the super absorbent resin was characterized by IR. It just needed 5min to preparation the super absorbent resin. Its liquid absorbency rate was about 1600 g · g-1 and 155 g · g-1 in purified water and 0. 9% NaCl solution.
