Abstract: PROBLEM TO BE SOLVED: To obtain a particulate polymer for binding physiologically active substances, e.g. proteins such as antibodies, nucleic acid substances, e.g. DNA, RNA or the like or physiologically active saccharide chain compounds to the particle surfaces and is useful in the fields of medicines and biology, more particularly obtain a particulate polymer in which the particles are made hydrophilic and the adsorption of undesired physiologically active substances (the nonspecific adsorption of the substances) is reduced to a lower level. SOLUTION: A monomer mixture that includes 10 wt.% of a radically polymerizable vinyl monomer bearing hydroxyl groups or methoxy groups is polymerized to obtain the particulate polymer for carrying the physiologically active substances.

Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic polymer particle which contains a magnetic substance and has carboxyl groups increased on the surfaces by suspension polymerization, by mixing a radically polymerizable vinyl monomer with a magnetic substance. SOLUTION: This polymer particle is obtained by mixing (A) 100 pts.wt. of radically polymerizable monomers containing 1-20wt.% of an unsaturated carboxylic acid [for example, (meth)acrylic acid] and (B) 5-200 pts.wt. of a magnetic substance (for example, Fe3 O4 ), dispersing them in water and polymerizing them with (C) an oil-soluble polymerization initiator (for example, benzoyl peroxide) and treating the formed particle with an organic base such as an amine and/or a water-soluble solvent such as acetone.
