Viscosity, Ultrasonic, Refractometric and Morphological Studies of PEO/HPMC Blend in Water at 300 C and 500 C


Measurements of Viscosity, Ultrasonic velocity, Refractive Index and SEM Studies of PEO/HPMC (Polyethylene oxide /Hydroxypropylmethylcellulose) blends in water were carried out for different blend compositions at 300 C and 500 C. Using the viscosity data, interaction parameters µ and α were computed to determine miscibility. These values revealed that PEO/HPMC blends were miscible when the HPMC content in the blend was 50% and above at 300 C and 500 C. The results were further confirmed by ultrasonic velocity, Refractive index measurements, and Morphological Studies.
