ABSTRACT:
Grains of a totally porous, hydroxyl group-containing, nonionic and hydrophilic synthetic cross-linked polymer having alcoholic hydroxyl and ether groups as main hydrophilic groups and having as a main skeleton a chemical structure including carbon atoms, hydrogen atoms and oxygen atoms bonded through single bonds, said synthetic polymer having a hydroxyl group density of 1 to 15 milliequivalents/g, a specific surface area of 5 to 1000 m.sup.2 /g and a water regain of 0.3 to 3.0 g/g. Such grains have been found to be a packing material or gel for high speed, aqueous gel permeation chromatography. The packing material of the present invention which comprises grains of a hydroxyl group-containing nonionic and hydrophilic synthetic cross-linked polymer has a chemical structure obtained by reacting a totally porous, hydroxyl group-containing, nonionic polymer with a polyfunctional substance capable of reacting with the hydroxyl groups of said polymer while forming cross-linking ether groups.
