Structure of comb-shaped liquid crystalline polysiloxane with phenyl benzoate mesogenic side group has been studied. The analysis of the scattering intensity and calculation of the Patterson function of polymer samples oriented in the magnetic field over a wide temperature range have been performed. On the base of these data the structural model of mesogenic groups packing has been suggested.
