Miscibility of Polycarbonate/Polyvinylpyrrolidone and Polycarbonate/Polyethylene Oxide in Chloroform by Viscosity, Ultrasonic and Refractometric Methods

摘要

Miscibility studies of polycarbonate/polyvinylpyrrolidone (PC/PVP) and polycarbonate/polyethylene oxide (PC/PEO) in common solvent chloroform were carried out in different percentages of the blend compositions. The viscosity, ultrasonic velocity, refractive index and density were measured at 30 deg C. The interaction parameters were obtained using the viscosity dta to probe the miscibility. The obtained results were confirmed by the ultrasonic velocity, density and refractive index measurements.
