  • Publication number: 20040157209
    Abstract: The present invention relates to molecularly imprinted polymers comprising tailor-made recognition sites for a target in which said recognition sites are located at or close to the surface of the polymer and/or of pores in the polymer. The molecularly imprinted polymer comprising tailor-made recognition sites for a target is obtainable by polymerising functional monomers and, optionally, cross-linked, optionally in a reaction solvent, in the presence of at least one template immobilised on a support material in a polymerisation process, whereby non-covalent or covalent are formed between said functional monomers and said immobilised template(s), and removing said template(s), and said support material from the molecularly imprinted polymer.

  • Patent number: 6333426
    Abstract: Opticallly active adsorbents based on network polymerized derivative 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.
