Abstract: A liquid-crystalline polymer comprising the repeating units of the general formula (I) ##STR1## in which: k is an integer from 1 to 30; andR.sup.1 is ##STR2## where: X is --COO-- or --OCO--; andR.sup.2 is --COOR.sup.3, OCOR.sup.3, or --OR.sup.3where:R.sup.3 is ##STR3## R.sup.4 and R.sup.5 being each independently --CH.sub.3, a halogen radical, or --CN, m and n being each independently an integer from 0 to 10 with the proviso that n is not 0 when R.sup.4 is --CH.sub.3, p being 0 or 1, and C marked with * being an asymmetric carbon atom.The polymers of the present invention exhibit a ferroelectricity even at temperatures around room temperature and as well such a high speed of response to external factors that they can be used for displaying motion pictures, and the polymers may also be advantageously used as display elements for large displays or curved displays.
