- Аннотация: The structure and properties of the new material derived from binol (BCA), multifunctional chiraladditive to liquid crystals (LC) with a high optical activity and the presence of free carboxylic groups in the molecule, are studied. The analysis of the thermal behavior of BCA is done by means of DSC, rheology methods, dielectric, and IR spectroscopy. The agreement between the rheological and dielectric data indicates the similar relaxation mechanisms, described within the WLF model. The analysis of the IR spectra proves the change in dielectric and rheological parameters induced by the variation in the structure of associates of hydrogen-bonded complexes. The modification of the sizes and quantity of the connected structures with the temperature may result in the possible appearance of nonlinear effects in LC composites associated with the simultaneous complex change in the dielectric and rheological properties.
