摘　　要： 研究以微波辐射为辅助引发条件和反应的热源,利用纸浆纤维与单体丙烯酸在复合引发剂(硝酸铈铵和过硫酸铵)引发下进行非均相接枝共聚反应,合成高吸水性树脂.经过选择和优化得其最佳合成工艺条件:单体体积与纸浆干重比为10∶1,引发剂硝酸铈铵与过硫酸铵的用量为0.04mL和0.08mL,中和度为85%,在微波炉内引发(3min+3min)后,反应3min,所得树脂吸水率为1204g/g,吸盐水(0.9%NaCl)率为99g/g. A super water-adsorbent resin was synthesized from pulp cellulose and acrylic acid by graft copolymerization and reaction under microwave irradiation in heterogeneous phases and using ceric ammonium nitrate and ammonium persulfate as initiators.The optimal synthesis conditions were as following:first initiating for 3 min by 0.04 mL ceric ammonium nitrate and 0.08 mL ammonium persulfate as initiators,then reacting for 3 min under microwave with 85% of monomer neutralization degree and 10∶1 of proportinn of monomer volume to dry pulp weight. The resin prepared has a super water absorption capacity of 1 204 g/g for deionized water or 99 g/g for 0.9% NaCl saline water.
