摘　　要：cyclodextrin polymer cross-linked with epichlorohydrin was prepared. A colloid liquid with polyphenylsiloxane as diluent was prepared from β-cyclodextrin polymer(0.26 g) treated for 0.5 h by ultrasonication in mixed solvent (10 mL) of isopropyl ether, methylene dichloride and benzene (at volume ratio of 2∶1∶2). The β-CD polymer liquid is coated superdynamically on the capillary columns as stationary phase for gas chromatography. Chromatographic properties such as column efficiency, thermal stability, polarity and life of the stationary phase have been determined and xylene isomers and a series of enantiomers have been separated successfully on the capillary columns with prepared stationary phases.cyclodextrin polymer cross-linked with epichlorohydrin was prepared.
