(57) [Abstract] [Purpose] It is possible to easily adjust the amount of exchange groups and the pore volume, to have a high strength, and to produce a cation exchange resin having a phosphoric acid group suitable for the separation and adsorption of bio-related substances. Providing a way. [Structure] 90 to 30 parts by weight of glycidyl monovinyl ester and polyvinyl ester of polyhydric alcohol 10 to 7 A total of 100 parts by weight of 0 parts by weight is subjected to aqueous suspension polymerization in the presence of an organic solvent which is incompatible with water, and the crosslinked polymer particles obtained are reacted with phosphoric acid. This is a method for producing an ion exchange resin. |
