Abstract
The liquid-crystalline polymeric composition of the invention comprises (A) a non-liquid-crystalline polymeric compound and (B) a low-molecular liquid-crystalline compound each having a proton donor and/or a proton acceptor in the molecular structure and the low-molecular compound has a chiral smectic C phase. By virtue of these functional groups forming hydrogen bonds between the components, the liquid-crystalline polymeric composition of the invention is not a mere blend of the components liable to cause phase separation but is imparted with greatly increased stability and uniformity of the blend as well as responsivity of high speed.
