| 摘 要： | 由于具备优良的生物相容性及大量可以用于修饰的羟基，交联聚乙烯醇球可以用作医用吸附剂的载体。本文对交联聚乙烯醇球的制备条件进行了详细研究，并讨论了环氧基的固载条件，分析了球的交联度、单体浓度对交联聚乙烯醇珠的粒径分布、溶胀度和环氧基团固载量的影响。

| Abstract: | The crosslinked poly (vinyl alcohol) bead was widely used as medical adsorbent because it has plenty of hydroxyl group. In this paper, the conditions for the preparation of poly(vinyl alcohol) bead and immobilization of epoxy were studied in detail. The effects of the ratio of crosslinker and monomer concentration on the bead size distribution, swelling ratio and the amount of immobilized epoxy were also investigated. |
