Abstract
One purpose of the present invention is to provide a liquid-crystal compound which exhibits liquid crystallinity at low temperatures. Another purpose of the present invention is to provide a thermally responsive material which exhibits liquid crystallinity and rubber elasticity at low temperatures (around room temperature) ever, though a large amount of a liquid-crystal compound is contained therein, and a method for producing this thermally responsive material. A liquid-crystal compound according to the present invention is obtained by adding an alkylene oxide and/or styrene oxide to a mesogenic group-containing compound that has an active hydrogen group.

A liquid-crystal compound obtained by adding an alkylene oxide and/or styrene oxide to a mesogenic group-containing compound that has an active hydrogen group.
A method for producing a thermally responsive material, the method comprising:
- a step A of adding an alkylene oxide and/or styrene oxide to a mesogenic group-containing compound having an active hydrogen group to obtain a liquid-crystal compound;
- a step B of mixing the liquid-crystal compound and a compound that reacts with the active hydrogen group of the liquid-crystal compound under no solvent condition to obtain a raw material composition for a thermally responsive material;
- and
- a step C of curing the raw material composition for a thermally responsive material at a temperature at which liquid crystallinity is exhibited.
