Ferroelectric liquid-crystalline polymer and epoxide usable for preparing the ferroelectric liquid-crystalline polymer

摘要

A ferroelectric liquid-crystalline polymer consisting essentially of at least one repeating unit represented by the following general formula:wnereink is an integer having a value of 2 to 30;X is -COO- or -OCO-; andR² is -COOR³, -OCOR³ or -OR³;whereinwhereineach of R⁴ and R⁵ is independently -CH_s, a halogen atom or -CN;each of m and n is independently an integer having a value of 0 to 10, with the proviso that when R⁴ is -CH₃, n is not an integer having a value of 0;p is an integer having a value of 0 or 1; andC marked with *is an asymmetric carbon atom.
