✦ Synopsis

Brillouin spectroscopy was used to study the elastic properties of polyethylene glycol solutions in water, benzene and toluene. It has been shown that the spectroscopic features, characterizing the elastic properties of polymer solutions being under study, strongly depend on both polymer concentration and the kind of solvent. The non-monotonic character of the concentration dependencies of the hypersound velocity and adiabatic compressibility indicate the occurrence of the polymer-solvent interactions.
