Abstract:The ultrasonic velocity, adiabatic compressibility, relaxation time, relaxation amplitude and Rao's number are reported for poly (methylmethacrylate) (PMMA) solution in Dioxane at different concentrations and temperatures. The results show a non linear increase of ultrasonic velocity, density, viscosity, relaxation time, relaxation amplitude with increasing PMMA concentration. However, the adiabatic compressibility and Rao's number decrease with increase in concentration of PMMA indicating the interaction between the Dioxane and PMMA molecules.
