Abstract
This invention relates to a method for preparing globular, hydrophilic copolymers which have reticulated internal structures and are suitable for gas and gel chromatography. The method comprises polymerization by suspension polymerization methods of hydrophilic and hydrophilic monomers in aqueous medium in the presence of a component which prevents transfer of the hydrophilic monomer into the aqueous medium and the solubility of the aqueous medium in the monomeric phase.
