MACROPOROUS GEL, ITS PREPARATION AND ITS USE

摘要

A macroporous gel for chromatographic separations and separations in an electrical field obtainable by polymerizing, optionally in presence of a filler, an aqueous solution of one or more water soluble monomers under freezing at a temperature below the aqueous solvent crystallization point, at which temperature the solvent is partially frozen with the dissolved substances concentrated in the non-frozen fraction of solvent, to the formation of a cryogel, which can further be modified by introducing a member selected from the group consisting of ligands, charged groups, dyes and hydrophobic groups.
