Orientational ordering of four liquid-crystalline acrylates induce,~ c;v, the surface of KBr plates over a wide temperature range was studied by the IR dichroism techmqL,~. "R spectra of homogeneously aligned samples were used to calculate the angles between the direction oL the transition moment fo/" a series of vibrations of the mesogenic fragment and its long axis. A method for calculation of the homeotropic orientation parameter of molecnles was proposed. The orientation parameters of homogeneously and homeotropically aligned samples in the nematic, smectic (A), and chiral smectic (I and H) phases were calculated. The in situ photopolymerization of acrylates in the smectic phases occurs with retention of the orientational ordering in the polymer films formed.
