Abstract

Provided is a temperature responsive adsorbent prepared by immobilizing a copolymer containing at least N-isopropylacrylamide to a base material surface. The copolymer has at least a strong cation exchange group. In addition, the copolymer contains the strong cation exchange group in an amount of 0.01 to 5 mol % relative to N-isopropylacrylamide in terms of monomer.
