摘要：
Conformational properties of molecules of the thermotropic aromatic polyesters containing mesogenic and flexible very long oxyethylene fragments are discussed on the basis of molecular hydrodynamic investigations. Changes in conformational properties and equilibrium flexibility of molecules, caused by changes in the way of biphenylene fragments insertion into the chain are analyzed. Intramolecular orientational mobility of mesogenic fragments is characterized by a dimentionless parameter lambda/A.
