PROBLEM TO BE SOLVED: To provide a new liquid-crystalline polymer capable of responding at ≤100°C or even at room temperature, especially a liquid-crystalline polyaminourethane which is a main chain type thermotropic liquid-crystalline polymer; and to provide a production intermediate effective in producing the liquid-crystalline polyaminourethane; and a method for producing the liquid-crystalline polyaminourethane and its production intermediate.SOLUTION: A main chain type thermotropic liquid-crystalline polymer having a bent part introduced into a main chain through amino group and benzene ring, and a photo-responsive mesogen core, a urethane bond and a flexible methylene chain introduced into the main chain is produced by reacting a compound having an ω-halogenated alkyl group with an amine and polymerizing with a diisocyanate. |
