Miscibility characteristics of blend, carbohydrate polymer ( Arabic gum ) and Poly (vinyl pyrrolidin) (PVP) in common solvent water were studied at different weight percentage by ultrasonic wave velocity, viscometry, and density techniques at 30°C. The acoustical parameters such as, relaxation amplitude (α/f2), absorption coefficient (), relaxation time (τ), acoustical impedance (Z) and adiabatic compressibility (β), are calculated. The results are interpreted in terms of molecular interaction between the components of the mixtures.
