摘　　要：以造纸黑液、丙烯酸(AA)、丙烯酰胺(AM)为原料,以过硫酸铵(APS)为引发剂,采用溶液聚合法制备了木质素接枝共聚丙烯酸-丙烯酰胺高吸水树脂;采用红外光谱对树脂进行了初步表征,测定了树脂的吸水性能;利用控制变量法研究了单体配比、丙烯酸中和度、引发剂用量、反应温度对树脂吸水倍率的影响;最佳合成条件为:NAM:NAA=0.2,AA中和度为60%,引发剂用量为0.1%,聚合温度为70℃,此时树脂对去离子水的吸水倍率为730g·g-1。In the black liquor of papermaklng, acrylic aeld （AA） and acrylamide （ AM ） as raw materials, ammonium pemul- fate （APS） as initiator, lignin graft copolymerization of acrylic acld - acrylamide super absorbent resin is prepared by solution polymerization. The rosin were charaoterized by infrared spectra,water absorption resin were determined. The use of ratio of monomers, neutralization degree of acrylio acid, effects of initiator concentration and reaction temperature on the water ab- sorbency of the control.llng variables method,the optimum synthesis conditions were：NAM ：NAA = 0.2, AA neutralization de- gree is 60% ,the dosage of initiator is 0. t% ,the polymerization temperature was 70 ℃. Water absorbency resin in delon- ized water is 730 g· g^-2.
