Almract--Adiabatic compressibility measurements of solutions of bisphenol A polycarbonate in a number of different solvents, including a 0-mixture, have been carried out. The results were used to estimate the number of solvent molecules solvating each repeat unit of the polymer. Tentative mechanisms

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
Adiabatic compressibility data for polystyrene, using samples of various molecular weights dissolved in toluene, are reported as a function of concentration. These data are compared with calculations of the incremental compressibility obtained from viscoelastic and longitudinal acoustic relaxation s
