Аннотация:Copolymers have been synthesized in which chiral monomer units are combined with those of a tilted smetic homopolymer. The copolymers with the proportion of chiral units not exceeding 37% form a Surn:x-wiley:02321300:media:CRAT2170270825:tex2gif-stack-1 phase and have therefore ferroelectric properties. Temperature dependences of the pyroelectric coefficient, spontaneous polarization and relaxation time have been mesured for a series of ferroelectric LC copolymers.
