Spherical porous fine particles of a cross-linked polymer can be obtained in the continuous phase by subjecting a mixture of a monovinyl aromatic compound and a polyvinyl aromatic compound to aqueous suspension polymerization in the presence of a paraffin wax with use of an initiator. This product is very suitable as a filler for gel permeation chromatography. Ion exchange groups can be introduced into the obtained polymer and a column filler suitable for ion exchange chromatography of amino acids, substances related to nucleic acids, proteins and the like is thus obtained. |
