Notes:
A review is given in the field of liquid crystalline polymers having mesogenic groups in side branches and in the main chain. Conditions for liquid crystalline state formation are discussed in relation with chemical structure of monomeric units, molecular mess and type of mesogenic groups. Pathways to synthesize nematic, smectic, and cholesteric mesophases in polymers are discussed, peculiarities of structure and properties of polymeric mesophases and models of chain packing in them are analyzed. Electrooptical properties of such systems, when an electric and magnetic field is applied, are discussed-Frederick's effect, electrohydrodynclmic instability, “guest-host” effect, cooperative structural transi- tion induced by electric field, and some others. The possible directions of application of polymeric liquid crystals are considered.
