耐电解质高吸水性树脂

Recent Developements of Anti-electrolytic Superabsorbent Polymer

在简述高吸水性树脂吸水机理的基础上 ,综述了改善高吸水性树脂耐电解质性能的四种途径 ,结合聚合方法重点讨论了提高亲水性。

The main four approaches to improve the anti\|electrolytic property of superabsorbent polymer were reviewed in this paper,including incorporation of nonionic monomer or longchain hydrophobic monomer,inproving the hydrophilic property of polymer,and synthesis and application of polyampholyte.Copolymerization of nonionic monomer,for example acrylamide,with AA is a usual way,but the effect is very limited.Improving the hydrophilic property of polymer is an effective way for the synthesis of oil in water emulsion thickener,the methods of improving the hydrophilic property of relevant monomers were also discussed.Incorporation of longchain hydrophobic monomer is a new and more effective way to improve the anti\|electrolytic property of superabsorbent polymer;Considering different modes of polymerization,this method was reviewed in great details.The synthesis and application of polyampholyte,which exhibits antipolyelectrolyte behavior in solution,were also reviewed;but the cost of this approach is relatively higher.
