Abstract

Optically active adsorbents based on network polymerized derivatives of dicarboxylic acids, diamines or diols which are chemically bonded to a carrier. The derivatives can be polymerized by radical polymerization or through hydrosilylation in the presence of a solid carrier. The optically active adsorbents are usable for chromatographic separation of racemic mixtures of enantiomers.
