Abstract:
To provide a method for producing polymer particles from an acrylamide monomer by a normal phase suspension polymerization method, polymer particles, a packing material for a chromatography column using the particles, and a chromatography column. A method for producing polymer particles, comprising dispersing a monomer composition comprising a multifunctional monomer having a plurality of N-substituted acrylamide groups in an aqueous medium; and polymerizing the dispersed monomer composition.
