The solutions of polystyrene and poly ether sulfone blends of different compositions were prepared in a common solvent. The miscibility of these blends was probed by viscosity, ultrasonic velocity and polarized optical microscopic techniques. The interaction parameters of these blends of different compositions were computed with the relevant equations. The immiscible nature of these blends was confirmed by the ultrasonic velocity and polarized optical microscopic methods. The immiscible nature of these blends suggests that these two polymers are favorable for preparing polymer alloys using a suitable compatibilizer
