摘要：

The novel approach of using Ion-exchange chromatographic supports for size exclusion chromatography of neutral and cationic water-soluble polymers is presented. A quaternary ammonium group, a strong anion exchanger, has been bonded to the surface of porous silica glass in the pore size range from 40 to 25 000 A. Chromatograms are shown of poly(2-vinylpyridlne) and dextran molecules using acidic salt solutions as eluents. Molecular weight calibration graphs, theoretical plate height plots, concentration effects are discussed in detail. © 1979, American Chemical Society. All rights reserved.
