A material which expresses its critical solution temperature even in an aqueous solution containing a buffer or salt, and at the same time, shows small variation width of the critical solution temperature even when concentration of salt or the like contained in water, a buffer liquid or the like is different, interacts with a substance such as a component in the living body and can therefore be used efficiently in the isolation of substances, is provided. A monomer represented by a formula (1) and a thermoresponsive polymer which contains said monomer as a polymerization component.
