ABSTRACT OF THE DISCLOSURE 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 polymer- ized 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.
