Essay

Works are defending, in which the acoustic spectra and elastoviscous properties of liquid polyethers, of are systematically investigation, as well as the calculation methods of thermodynamic characteristics of viscous flow and acoustic spectra in liquid polyethers. Some models making it possible to operete the calculations of acoustic properties of liquid polyethers. The thermodynamic as well as kinetic parameters of the relaxation processes studied are calculated. The results, that were obtained, show that the model of the structural relaxation proposed is informative enough to understand the peculiarities of the relaxation phenomena in polyethers.
