摘要：
Copolymers have been synthesized in which chiral monomer units are combined with those of a tilted smectic homopolymer. The copolymers with the proportion of chiral units not exceeding 37% form a S(F)* phase and have therefore ferroelectric properties. Temperature dependences of the pyroelectric coefficient, spontaneous polarization and relaxation time have been measured for a series of ferroelectric LC copolymers.
