Abstract
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.
