将烯丙基缩水甘油醚与丙烯酰胺共聚合成带环氧基的亲水高分子，并利用其共交联木质素制备木质素基吸水树脂，考察了木质素用量、丙烯酰胺与烯丙基缩水甘油醚的配比、pH 等对树脂吸水性能的影响。结果表明，木质素基吸水树脂具有 pH 敏感性，吸水倍率随 pH 增加而增大；吸水树脂的吸水率随着木质素用量的增加而降低，增加烯丙基缩水甘油醚用量，吸水树脂的交联密度增加，其吸水率降低。当木质素用量为5 g，丙烯酰与烯丙基缩水甘油醚的配比为0.06：0.03时，制备的木质素基吸水树脂在 pH =9的水溶液中吸水倍率为36.3 g/ g。

Water absorbent resin based on lignin were synthesized by the cross-linking of lignin with the hydrophilic polymer prepared by the copolymerization of allyl glycidyl ether( AGE)and acrylamide (AM). The influence of the content of lignin,the mass ratio of AM to AGE,and pH on water absorbency performance of the resins were investigated. The results showed that the water absorbent resins exhibited pH sensitivity,the swelling ratio increased with pH. The swelling ratio of resins reduced with the increas-ing amount of lignin. The crosslinking density of water absorbent resin increased with the increase of the content of allyl glycidyl ether,which resulted in the reduce swelling ratio of water absorbent resins. The water absorption ratio of resin are 36. 3 g / g when the amount of lignin is 5 g,and the mass ratio of AM to AGE is 0. 06 : 0. 03.
