Zusammenfassung:A theoretical description of the dynamic phenomena in liquid-crystalline polymeric systems in periodic mechanical disturbances in terms of the shear modulus and the loss modulus has been given. The rheological characteristics (dynamic viscosity, accumulation modulus, loss modulus, and others) of a synthesized sample of a liquid-crystalline polymeric system -- aromatic polyamide -- and the critical concentration of its transition from the isotropic state to a liquid-crystalline phase have been determined experimentally.[PUBLICATION ABSTRACT]
