Abstract
Physical properties of composite materials based on 4-cyanophenylbenzoate derivatives were investigated. Compositions of mixtures were determined and their phase transition temperatures were measured. Temperature dependences of the dielectric permeability and refraction index were obtained. The dielectric anisotropy and optical anisotropy were calculated. The comparative analysis of mesomorphic and anisotropic properties of composite liquid crystal materials based on 4-cyanophenylbenzoate derivatives and commercial mixtures based on cyanobiphenyls was carried out.

Keywords: liquid crystal mixtures, mesomorphic properties, dielectric anisotropy, refraction index, optical anisotropy
