(57) [Summary] [Structure] Separation resin in which poly-N-isopropylacrylamide is supported on porous polymer particles, the resin as organic polymer particles, and a crosslinkable polyvinyl monomer from 25% by weight. After impregnating 100% by weight of a vinyl monomer, a radical polymerization initiator and a porosity-imparting solvent, the particles are suspended in an aqueous medium, and the temperature of the suspension is raised, and N-isopropyl is added during the polymerization reaction. A method for producing by adding acrylamide and a water-soluble polymerization initiator to the suspension. [Effect] The present invention provides a separating resin whose separation characteristics can be largely changed depending on temperature, which is impossible with a conventional separating agent. It is intended to provide a separating resin which can be separated by changing |
