| 摘 要： | 大孔乙酸乙烯酯－异氰尿酸三烯丙酯共聚物树脂经醇解生成亲水性的交联聚乙烯醇，然后相继与环氧氯丙烷和二乙胺反应，合成出含二乙基氨基羟丙基的阴离子交换剂，研究了交联聚乙烯醇环氧基化的最佳条件，发现以二甲基亚砜作溶剂能够显著地提高活化程度，反应时间以３ｈ为最佳，并研究了该阴离子交换剂的交换量、亲水性、热稳定性、溶胀稳定性，发现它具备常压分离蛋白质所需的基本性能，是较为理想的生化用的离子交换剂。

| Abstract: | An anion exchange resin with diethylamino groups supported by cross-linked poly(vinyl alcohol)was synthesized from poly(vinyl acetate-co-triallyl isocyanurate)in threesteps.Its chemical and physical structures,properties,and thermal stability were studied indetails.The results showed that the anion exchanger was suitable for the separation of pro-teins or enzymes. |
