摘　　要：以丙烯腈 /丙烯酸 /二乙烯基苯交联共聚 ,碱性水解制备耐水解的高吸水树脂。探讨了单体比例、聚合反应和水解反应等最佳制备条件。实验结果表明 ,共聚物中引入亲水性的丙烯酸单体及在聚合反应体系中加入适量水 ,可显著地改善共聚物的水解工艺。该高吸水树脂价格低廉、耐水解性能好 。In this work,anti-hydrolyzing high water-absorbent was prepared by polymerizing acrylonitrile,divinylbenzene and acrylic acid,followed by hydrolyzing the obtained polymer in an aqueous solution of NaOH ldeal technical conditions of processing,such as monomers ratio,polymerizing condition,and hydrolyzing condition,were discussed The results revealed that the hydrolysis processing could be improved by adding acrylic acid as comonomer and a suitable quantity of water to the polymerizing systerm The water-absorbent,had lower price,good anti-hydrolyzing and could be used repeatedly
