Abstract
PURPOSE:To provide a copolymer having liquid crystal property, ferroelectricity near room temperature, and a high speed of response to an external factor and capable of providing dynamic display, by constituting it from a copolymer of a molecular structure containing three specified kinds of recurring units. CONSTITUTION:A liquid crystal copolymer is prepared from a copolymer having a molecular structure containing recurring units of formulas I, II and III (wherein n is 1-10, R1 is a 1-20C alkyl chain, R2 is any one of formulas IV, V, VI and VII, and C* is an asymmetric carbon). This copolymer can be obtained by polycondensing a monomer comprising an optically active branched alkyl group-containing ester-diol of formula VIII with a monomer which constitutes a recurring unit of formula II (e.g., methanediol) and terephthaloyl chloride. The obtained liquid crystal copolymer can be molded into a film, and can be utilized for liquid crystal displays, electrooptical shutters, etc.
