Title: Comb-like liquid crystalline polymers with side groups modelling the smectic type of liquid crystal
Abstract: A description is given of the synthesis of several new comb-like polymers containing mesogenic groups in the side branches, simulating the structure of low molecular weight smectic type liquid crystals. The polymers obtained are able to form enantiotropic liquid crystalline phases, the type of which according to the terminology used for low molecular weight liquid crystalline compounds, may be defined as smectic. Thermodynamic boundaries of the liquid crystalline state were determined in the polymers synthesized, which enabled the liquid crystalline state in these polymers to be determined as a thermodynamically stable phase with spontaneous anisotropy of properties (particularly optical anisotropy). A typical feature of the structure of the polymers studied is the existence of layer ordering of side groups, which together with the packing of mesogenic groups ensures liquid crystalline properties. Mesogenic groups alone participate in the formation of crystalline packing in these polymers, whereas methylene chains, together with the main polymer chain, are in the amorphous phase.
