<p>A polar polymeric adsorbent based on glycidyl esters, which consists of a macroporous copolymer containing 3-70 percent of polymerized monomeric units containing epoxy groups, selected from the group comprising glycidyl methacrylate and glycidyl acrylate, 97-30 percent of a crosslinking agent selected from the group comprising alkylene diacrylate, alkylene dimethacrylate, hydroxyalkylene diacrylate, hydroxyalkylene dimethacrylate, where the alkylene contains 1-6 carbon atoms, and divinylbenzene, and optionaily, up to 30 percent of polymerized monomeric units containing nitrile groups, selected from the group comprising acrylonitrile and methacrylonitrile. The polymeric adsorbent of the invention is particularly suitable for use in gas and liquid chromatography.</p> |
