摘　　要：将β 环糊精分子用环氧氯丙烷预交联后 ,与淀粉、丙烯腈混合 ,用硝酸铈铵作引发剂接枝共聚 ,经水解可得拥有疏水空腔的β 环糊精改性高吸水树脂。该吸水树脂除具有良好的吸水和保水性能外 ,还对药物、香料等疏水性有机分子具有良好的包合或吸附作用 .The functionallized super water absorbing starch resin with β cyclodextrin was prepared by graft copolymerization of acrylonitrile onto a mixture of starch and prepolymerized β cyclodextrins which had been cross linked by epoxy chloropropane. Apart from strong water absorption and water retention power,This functionallized water absorbing resin with hydrophobic cavities also has good inclusion abilities to organic molecules such as drugs,flavours,etc.
