A. Purkina et al., PECULARITIES OF LIQUID-CRYSTALLINE ORDER FORMATION IN POLYESTERS WITHIRREGULAR CHEMICAL-COMPOSITION, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 299, 1997, pp. 199-203
Formation of liquid crystalline (LC) order in thermotropic main-chain
random copolymers (containing mesogens of one type and spacers of diff
erent lengths) were investigated by IR spectroscopy, DSC, X-ray and po
larized microscopy methods. It was demonstrated that in such copolymer
s (CPLs) smectic liquid crystalline (LC) order can exist. Peculiaritie
s in spacers behavior during transition to LC state are found, Conclus
ion about the dependence of the mechanism of smectic LC order formatio
n on chemical structure of rigid components of CPLs is made.
