| 摘 要：采用過(guò)硫酸銨作為引發(fā)劑，N，N-二甲基雙丙烯酰胺作為交聯(lián)劑，通過(guò)水溶液共聚法制備了丙烯酸、丙烯酰胺、丙烯腈高吸水性共聚物，探討了合成過(guò)程中各種影響因素對高吸水性樹(shù)脂性能的影響。結果表明，當反應單體配比n（丙烯酸）∶n（丙烯酰胺）∶n（丙烯腈）=15∶4∶6，引發(fā)劑用量為單體總質(zhì)量的0.05%，交聯(lián)劑用量為單體總質(zhì)量的0.015%，反應溫度為80℃，反應時(shí)間為3 h，中和度為75%的條件下，所得高吸水性樹(shù)脂的吸去離子水能力可達990 g／g以上，吸0.9%氯化鈉溶液能力達190 g／g以上。 |

| Abstract：Acrylic acid /acrylamide/acrylonitrile copolymer as salt-resisting super absorbent resin was prepared by water solution copolymerization. The ammonium persulfate was taking as the initiator and N,N’-ethylenebisacrylamide as the cross-linking agent. The influences of various factors on the properties of absorbent resin were discussed. The results showed that: when the reaction monomer mole ratio of n(acrylic acid): n(acrylamide) :n(acrylonitrile) was 15:4:6; a initiator dosage was 0.05% of the monomer; cross-linking agent was 0.015% of monomer; reaction temperature was of 80℃; reaction time was of 3 h; neutralization degree was of 75%; the absorption capacity of the resin was more than 990 g/g in case of deionized water and more than190 g/g in case of 0.9% NaCl solution. |
