A ferroelectric liquid crystal polymer comprising the recurring units represented by the following general formula: ##STR1## in which k is an integer of from 1 to 30, R.sub.1 is ##STR2## R.sub.2 is --COOR.sub.3, --OCOR.sub.3, --OR.sub.3, or --R.sub.3, in which R.sub.3 is ##STR3## R.sub.4 is --CH.sub.3 or Cl, m is 0 or an integar of from 1 to 10, n is 0 or an integar of from 1 to 10, providing that n is not 0, when R.sub.4 is --CH.sub.3. The ferroelectric liquid crystal polymer of the present invention not only exhibits a ferroelectricity even at temperatures in the vicinity of a room temperature, but also has so fast response speed to the external factors as to be able to display motion pictures, and may be advantageously used as display elements for large size screens and a curved screens.
本发明涉及一种铁电液晶聚合物,其由以下一般式所表示的重复单元组成:##STR1## 其中k为1到30的整数,R.sub.1为##STR2## R.sub.2为--COOR.sub.3,--OCOR.sub.3,--OR.sub.3或--R.sub.3,其中R.sub.3为##STR3## R.sub.4为--CH.sub.3或Cl,m为0或1到10的整数,n为0或1到10的整数,但当R.sub.4为--CH.sub.3时,n不为0。本发明的铁电液晶聚合物不仅在接近室温的温度下表现出铁电性,而且对外部因素的响应速度非常快,可以显示动态图像,并且可以优势地用作大尺寸屏幕和曲面屏幕的显示元件。
