Title: Chiral adsorbents and preparation thereof as well as compounds on which theabsorbents are based and preparation of the compounds

Abstract: Opticallly active adsorbents based on network polymerized derivative ofdicarboxylic acids, diamines or diols which are chemically bonded to acarrier. The derivatives can be polymerized by radical polymerization orthrough hydrosilylation in the presence of a solid carrier. The opticallyactive adsorbents are usable for chromatographic separation of racemicmixtures of enantiomers.
