Bendes Y. The acoustic spectroscopy of series oligomeric glicols

Thesis is devoted to the study of the acoustic spectra and elastoviscous properties of polyethyleneglicols, polythetramethyleneglicols, and telechelic and halatotelechelic polymers, formedon their basis are systematically investigated, as well as the calculation methods of thermodynamic characteristics of viscous flow and acoustic spectra in oligomers glicols. The characteristics of modifiable influence of the length and the nature of end functional groups on the parameters of acoustic processes have been come out. The fact has established that molecular mechanisms rotational isomeric and structural relaxation processes. The calculations of their kinetic and thermodynamic parameters have been come out.
