FIELD: polymer materials.
SUBSTANCE: invention relates to preparation of liquid-crystal films and coatings from substituted poly-p-xylenes used as orienting layers in different electrooptic devices (symbol displays, liquid-crystal displays, light shutters, and the like) and provides a liquid-crystal polymer film preparation process, which consists in preparation of films from substituted poly-p-xylene via consecutively performing following steps in vacuum in three-phase reactor: sublimation at 0 to 350°C, pyrolysis of substituted cyclic di-p-xylene wherein substitutions have terminal mesogenous groups, condensation of resulting from pyrolysis substituted p-xylene and simultaneous polymerization thereof on a substrate at 150-320°C. Process is carried out at speed of formation of film on substrate from 0.00001 to 0.01 μm/min at residual pressure in system from 0.000001 to 0.5 mm Hg.
EFFECT: enabled preparation of liquid-crystal polymer materials, whose films are excellent orientants for liquid-crystal molecules.
