Ultrasonic, refractometric and viscosity studies of some polymer blends in solution
The polymer blend solutions of polyvinyl chloride/polystyrene and polyvinyl chloride/cellulose acetate in common solvent have been prepared in different percent of the components. The ultrasonic velocity, viscosity and refractive index have been measured at 30 degrees C The interaction parameters have been computed using the viscosity data to probe the miscibility. The obtained revelations have been confirmed by the ultrasonic velocity and refractive index data
Miscibility of PVC PMMA blend by the ultrasonic and refractive index method
The ultrasonic velocity and refractive index of polyvinyl chloride (PVC):polymethyl methacrylate (PMMA) blend solutions in cyclohexanone have been measured at 30 degrees C. The variation of these parameters with blend composition has been found to be linear, indicating the miscibility of PVC with PMMA. The results obtained have been compared with those obtained by the viscosity method. (C) 1999 Elsevier Science Ltd. All rights reserved
