Abstract
Abstract Methods of translational diffusion, sedimentation, viscometry and flow and electric birefringence were used in the study of conformational properties of a number of comb-like polymers containing mesogenic side groups in dilute solution. Quantitative data on the degree of equilibrium rigidity of the main chain of these polymers were obtained by using modern theoretical concepts and hydrodynamic data. The value of optical anisotropy and the equilibrium and relaxation electro-optical properties of comb-like thermotropic macromolecules indicate that these macromolecules exhibit high intramolecular orientational and dipolar order. It is shown experimentally that in a comb-like molecule the increase in the distance between the mesogenic group and the main chain is accompanied by a sharp decrease in this intramolecular order.
