PROBLEM TO BE SOLVED: To provide a material which exhibits a critical solution temperature even in a buffer solution and an aqueous solution containing a salt, reduces the amplitude of the critical solution temperature, even when the concentration of the salt or the like contained in water or a solution such as a buffer solution, interacts with substances such as biological ingredients, and can effectively be used for separating the substances. SOLUTION: A monomer represented by formula (1) (R<SP>1</SP>is H or methyl; R<SP>2</SP>is carbamoyl, or methyl, ethyl, propyl, butyl, pentyl, hexyl, cyclopentyl, cyclohexyl, cycloheptyl, methoxy, ethoxy, propoxy, butoxy, pentyloxy or hexyloxy whose one or more hydrogen atoms are substituted with one or more carbamoyl groups). A thermally responsible polymer containing the monomer as a polymerization component. COPYRIGHT: (C)2008,JPO&INPIT |
