PROBLEM TO BE SOLVED: To produce a critical solution temperature even in an aqueous solution containing a buffer solution or a salt, and at the same time, even if the concentration of salt or the like contained in a solution such as water or buffer solution is different, the fluctuation width of the critical solution temperature is small. Provided is a material that interacts with substances such as biological components and can be effectively used for separation. A monomer represented by formula (1) wherein R 1 is hydrogen or methyl, R 2 is carbamoyl or one or more hydrogens substituted with carbamoyl, methyl, ethyl, propyl , Butyl, pentyl, hexyl, cyclopentyl, cyclohexyl, cycloheptyl, methoxy, ethoxy, propoxy, butoxy, pentyloxy or hexyloxy) and a thermoresponsive polymer containing the monomer as a polymerization component.
