The miscibility studies of unsaturated polyester resin (UPR) blends with two different thermoplastics, polystyrene (PS) and polycarbonate (PC) in common solvent chloroform were carried out by viscosity, ultrasonic velocity, density, and refractive index methods. Two interaction parameters, μ and α were calculated using viscosity data for these blends. The positive interaction parameter values (μ and α > 0) obtained for the UPR/PS blend and the negative interaction parameter values (μ and α < 0) obtained for the UPR/PC blend indicate that the former is a miscible blend and the latter is an immiscible blend. These results were further confirmed by ultrasonic velocity, density, and refractive index measurements.
