Abstract
The densities, àand ultrasonic speeds, u of Poly (propylene glycol) 400 in ethanol, 1-propanol and 1-butanol have been measured at 30°C. By using the experimental values of àand u, the parameters adiabatic compressibility, intermolecular free length, available volume, acoustic impedance and relaxation strength have been computed. The variations of these parameters with composition of the mixture have been used to discuss the nature and extent of intermolecular interactions between the component molecules.
