| 摘 要： | 采用溶液聚合法,以丙烯酸(AA)和丙烯酰胺(AM)为单体,N,N’-亚甲双丙烯酰胺(NMBA)为交联剂,过硫酸铵为引发剂,制备了丙烯酸-丙烯酰胺共聚物吸水树脂,探讨了单体配比(mAA/mAM)、交联剂和引发剂用量对树脂吸水率的影响。结果表明:在65℃时,丙烯酸-丙烯酰胺共聚物吸水树脂的最佳制备条件为:丙烯酸和丙烯酰胺质量比为4:1,交联剂和引发剂用量分别为聚合单体(丙烯酸和丙烯酰胺)总质量的0.02%和0.4%。

| Abstract: | The poly(acrylic acid-co-acrylamide) absorbent resin was prepared by water solution copolymerization using acrylic acid(AA) and acrylamide(AM) as monomers,N,N'-Methylenebisacrylamide(NMBA) as crosslinker and ammonium persulfate(APS) as initiator.The effects of ratio of graft monomers(mAA/mAM),content of crosslinker and initiator on the properties of water absorbency were discussed.The results showed that the optimum reaction conditions were obtained as follows: mAA: mAM= 4: 1,dosage of crosslinker was 0.02% and initiator was 0.4% at 65℃. |
