摘要：Ultrasonic velocity(u), density(ρ) and viscosity(η) have been measured for the aqueous solution ofPolyvinyl alcohol. PVA is mixed with triply distilled water and acoustical parameters has been calculated for differentconcentration at 303k. From the experimental data, the acoustical and thermodynamic parameters are calculated. Theseacoustical parameters are used to study the nature and the strength of the molecular interactions. The stability constantvalues shows that the system is stable and stability is lost when the concentration of polymer is increased, therebyweakening the bond.
