摘　　要：报道了一种多孔球状淀粉接枝共聚物的合成．此球有很强的机械性能、良好的稳定性和较高的致孔率（30％～40％），平均孔径约为19．5nm．以其为载体固定化精化酶活力为1462IU／g干胶，比活为29．31IU／mg蛋白．Porous starch graft copolymers(PSGC) beads were synthesized and their proper-ties were studied. The PSGC beads prepared have good mechanical properties and high porosity(about 30%-40%), the pore size is about 19. 5 nm. The PSGC beads are stable in the range of pH 3-13 as well as in boiling water. They contain large amount of active groups making them suitable for use as support material for immobilized enzymes.
