The miscibility of Acacia (AC)/Poly (vinyl pyrrolidone) (PVP) and Acacia (AC)/Poly (ethyleneglycol) (PEG) blends in water at 30°C were studied using ultrasonic velocity and density measurements. The results of ultrasonic velocity and the derived acoustical parameters such as adiabatic compressibility (βad) and acoustic impedance (Z) have been used to discuss the miscibility/immiscibility of the blends under study. The conclusions drawn from these results indicate that AC/PVP blends are miscible whereas AC/PEG blends are immiscible. The miscible/immiscible nature of these two blends may be attributed to the intermolecular interactions between the constituent polymers. These investigations offer an entirely new and simple approach to study the compatibility of the polymer blends, which is in general obtained by the sophisticated techniques of thermal, dynamic, mechanical and electron microscopic analysis.

Abstract


The miscibility of Acacia (AC)/Poly (vinyl pyrrolidone) (PVP) and Acacia (AC)/Poly (ethyleneglycol) (PEG) blends in water at 30°C were studied using ultrasonic velocity and density measurements. The results of ultrasonic velocity and the derived acoustical parameters such as adiabatic compressibility (βad) and acoustic impedance (Z) have been used to discuss the miscibility/immiscibility of the blends under study. The conclusions drawn from these results indicate that AC/PVP blends are miscible whereas AC/PEG blends are immiscible. The miscible/immiscible nature of these two blends may be attributed to the intermolecular interactions between the constituent polymers. These investigations offer an entirely new and simple approach to study the compatibility of the polymer blends, which is in general obtained by the sophisticated techniques of thermal, dynamic, mechanical and electron microscopic analysis.
