Abstract
The results of investigation of liquid crystalline multicomponent systems C₁₂H₂₅O(CH₂CH₂O)₁₀H, C₁₂H₂₅O(CH₂CH₂O)4H/La(N0₃)₃•6H₂0/H₂0/C₁₀H₂₁OH has been presented. Concentrations, temperatures interval of mesophase existence and type of supramolecular organization were established by polarized optical microscopy. Decanol influence on mesogenic properties was established. Based on viscosimetry data analysis of the structure changes in the field of phase transition has been carried out. The conditions of shear deformation for mesophases are defined as non-linear plastic matter and are sufficiently described by Cаsson and Hershel – Bulkley models.
