    摘要: Method of chromatographically separating a mixture by contacting said mixture under chromatographic separation conditions with a chromatographic separation stationary phase comprising an N-acyl diazepine polymer. In a preferred form, the polymer has been rendered substantially alkali-stable by substitution for the hydrogen at the C3 position on the diazepine ring.
