中文摘要：

以丙烯酸和丙烯酰胺为单体,N,N-亚甲基双丙烯酰胺为交联剂,过硫酸钾为引发剂,采用水溶液聚合法制备了高吸水树脂。通过正交实验法研究了单体浓度、丙烯酸中和度、引发剂用量和交联剂用量对树脂吸水倍率的影响。最终获得了在蒸馏水中吸水倍率高达3114g/g,在质量分数0.9%NaCl溶液中吸水倍率达157g/g的高吸水树脂,该树脂能够用作稠化胶体的稠化剂来提高胶体的实用性能。

英文摘要：

The super absorbent resin was prepared by the polymerization of aqueous solution.The copolymerization was carried out using acrylic acid and acrylamide as monomer,N,N-methylene bisacrylamide as crosslinking agent and potassium persulfate as initiator.The effects of monomer concentration,the degree of acrylic acid,initiator dosage and crosslinker dosage on water absorbency were investigated by orthogonal test.The super absorbent resin was obtained,its water absorbency was 3114g/g in distilled water and 157g/g in 0.9wt% NaCl solution.It could be used as thickening agent to improve the thickening colloid practical performance.
