| abstract | PCT No. PCT/JP91/00859 Sec. 371 Date Mar. 5, 1992 Sec. 102(e) Date Mar. 5, 1992 PCT Filed Jun. 26, 1991 PCT Pub. No. WO92/01731 PCT Pub. Date Jun. 2, 1992.A liquid-crystalline copolymer comprising the repeating units represented by the following general formulas (* CHEMICAL STRUCTURE *) (1) and (* CHEMICAL STRUCTURE *) (II) wherein each of r and p is an integer of 2 to 5, q is an integer of 0 to 3, m is an integer of 1 to 20, and R1 is (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) (* CHEMICAL STRUCTURE *) or (* CHEMICAL STRUCTURE *) R2 being -COOR3, -OR3 or -OCOR3, R3 being (* CHEMICAL STRUCTURE *) each of R4 and R5 being -CH3 or a halogen atom, each of a and d being an integer of 0 to 10, b being an integer of 0 or 1, with the proviso that d is not 0 when R5 is -CH3, the repeating units (I) and (II) being present in the liquid-crystalline copolymer in a substantial molar ratio (I):(II) of 1:1, exhibits ferroelectricity even at a temperature neighboring room temperature and having a high response speed to changes of external electric fields. |
