A liquid-crystal copolymer developing ferro-electricity near room temperature and rapidly responding to a change in outer electric field, which comprises repeating units of general formulae (I) and (II) in a molar ratio of around 1:1, wherein r and p each represents an integer of 2 to 5; q represents an integer of 0 to 3; m represents an integer of 1 to 20; R¹ represents (a); R² represents -COOR³, -OR³ or -OCOR³; R³ represents (b); R⁴ and R⁵ each represents - CH₃ or halogen; a and d each represents an integer of 0 to 10; and b is 0 or 1, provided that d is not 0 when R⁵ represents - CH₃.
一种液晶共聚物,可在室温附近产生铁电性并对外部电场的变化迅速作出反应,它由通式(I)和(II)的重复单元组成,摩尔比约为1:其中 r 和 p 分别代表 2 至 5 的整数;q 代表 0 至 3 的整数;m 代表 1 至 20 的整数;R¹ 代表 (a);R² 代表 -COOR³、-OR³ 或 -OCOR³;R³ 代表 (b);R⁴ 和 R⁵ 各自代表-CH₃ 或卤素;a 和 d 各自代表 0 至 10 的整数;b 为 0 或 1,但当 R⁵ 代表-CH₃ 时,d 不为 0。
