High polymer, ferro-electric liquid-crystalline composition containing the high polymer and raw material of the high polymer.

摘要

This invention provides a high polymer having the following repeating unit (I), a diene compound which is represented by the following formula (II) and is a raw material of the high polymer: <CHEM> and a ferroelectric liquid-crystalline composition containing the high polymer and a low molecular weight smectic liquid-crystalline compound. The ferroelectric liquid-crystalline composition is easy to orient and exhibits a fast response against applied electric field.
