ABSTRACT:
Disclosed is a surface-modified polymeric adsorbent material comprising a porous post-crosslinked polymer as a substrate and at least one surface-modifying polymer. The porous post-crosslinked polymer comprises a polymer of at least one monoethylenically unsaturated monomer, wherein the polymer has been post-crosslinked in a swollen state in the presence of a Friedel-Crafts catalyst. A process for preparing the surface-modified polymeric adsorbent materials, and the use of these materials in the separation of organic compounds, enantioselective synthesis and resolution of racemic mixtures are also disclosed.
