“…The strength of ion-dipole attraction is directly proportional to size of the ion, charge, and the magnitude of the dipole, but inversely proportional to the distance between the ions and the dipolar molecules [9][10][11][12][13] of polymer solutions and has shown that ultrasonic velocity and its allied parameters provide more information on molecular interactions which are of the utmost importance for process involving polymer production and their uses [14]. In the present paper an attempt has been made to calculate adiabatic compressibility, acoustic impedance, intermolecular free length, and relaxation time by using measured values of ultrasonic velocities, densities, and viscosities at concentration range of 1.0%, 0.8%, 0.6%, 0.5%, 0.4%, and 0.3% at 35 ∘ C temperature.…”

Ultrasonic velocities, densities, and viscosities have been measured for the solution of polyvinyl alcohol in water at concentration range of 0.3% to 1% at temperature 35 ∘ C. Ultrasonic velocities have been measured using variable path ultrasonic interferometer at 1 MHz frequency. The acoustical parameters like adiabatic compressibility, acoustic impedance, intermolecular free length, and relaxation time have been calculated by using above-mentioned values of ultrasonic velocities, densities, and viscosities. The variation of these acoustical parameters is explained in terms of solute-solvent interaction in a polymer solution.
