Abstract
Synthesis of new liquid-crystalline comb-like polymers with oxygen-containing spacers and mesogenic cyanbiphenyl groups is described. Liquid-crystalline homo-polymers of acrylates and methacrylates, their copolymers and liquid-crystalline polysiloxane are obtained. It is shown that the incorporation of oxygen atoms in spacer leads to decrease of the clearing temperature. The mesophase types of the homopolymers and copolymers are determined.Keywords
