摘要：

Three side-chain liquid-crystalline polysiloxanes were prepared by hydrosilations of poly(dimethyl siloxane-co-methylhydro siloxane)s using a chiral smectic C vinyl monomer. All the polymers exhibit a subambient temperature glass transition, a chiral smectic C (S-C*) and chiral smectic A (S-A*) phase. The maximum spontaneous polarization (P-S) measured for the S-C* phase of polymer Ib is 368 nC/cm(2).
