Abstract

The Raman scattering spectra of polyethyleneglycols with different mean molecular weight have been obtained vs. concentration and temperature. The measurements were performed for compounds of mean molecular weight 1500 and 2000. On the basis of the characteristic frequency data of atomic group vibration in organic compounds, the bands observed in Raman spectra have been assigned. The temperature ranges of the phase transition and the change in the order parameters have been estimated from the temperature dependence of the phonon band parameters of the polymers studied. Moreover, the shape of the O - H band vs. polymer concentration has been examined.
