✦ Synopsis

Measurements of the propagation velocity of longitudinal sound waves may be used to provide information on the frequency dependence of the adiabatic compressibility. Data are reported for solutions of polyethylene oxide, polystyrene and poly-N-vinylcarbazole in toluene and for polyethylene oxide in carbon tetraehloride, water and cyclohexanone. These data illustrate the influences of polymer flexibility, molecular weight and strength of polymer-solvent interaction on the magnitude of the observed adiabatic compressibility at a particular frequency of observation.
