Abstract
Measurements of viscosity of poly methyl methacrylate (PMMA)/poly ethylene glycol (PEG) blends in tetra hydro furan (THF) as a common solvent, were carried out for different blend compositions at 30, 40 and 50°C. Using the viscosity data, interaction parameters µ were computed to determine miscibility. These values revealed that the blend was miscible when the PMMA content was more than 30% of the blend. Further, the results revealed that the change in temperature has significant effect on the miscibility of PMMA/PEG polymer blends. The simple of (PMMA/PEG) blends were characterized by using (FTIR).
