摘　　要：L-proline was linked onto cross-linked polystyrene to give chiral chelating resin (1). The copper (Ⅱ) chelate of resin (1) was used as the chiral stationary phase for the chromatographic resolution of DL-amino acids. However, the hydrophobicity of polystyrene causes an amino acid to transfer slowly during chromatographic process so<正> L-proline was linked onto cross-linked polystyrene to give chiral chelating resin (1).
