摘要：

Several new chiral liquid crystal siloxane homopolymers and copolymers have been synthesized and studied as to their mesomorphic and ferroelectric behaviour. Almost all of them exhibit chiral smectic C phases over wide temperature ranges. DSC and X-ray measurements are presented; spontaneous polarizations, response times and tilt angles are also given. Some of the spontaneous polarizations are very high, more than 100 nC/cm2, and the response times are found to be among the fastest for liquid-crystalline polymers, less than 1 ms.
