Abstract
Optical and electrooptical properties of a number of thermotropic meso genic aromatic polyesters were studied in dilute solutions by means of flow birefringence and electrical birefringence. Flow birefringence i nvolves large-scale mobility, whereas equilibrium electrical birefring ence is associated with local reorientation of polar, anisotropic meso genic fragments in the polymer chain. The optical and electrooptical c haracteristics of the studied aromatic polyesters correlate with aniso tropic and dipolar architecture of their macromolecules.
