In this study, we measure the viscosity of polyvinyl alcohol (PVA)/polyethylene glycol (PEG) blends in dimethyl solfoxide (DMSO) as a prevalent solvent. We carried out at the different percentages of the blend compositions (70/30,60/40, 50/50, 40/60, and 30/70) at 30, 40 and 50Cº respectively. The viscosity information, μ interaction parameters have been computed to determine miscibility. These values proved that the blend was miscible in the all-percentages of the two content. Further, the results revealed that the change in temperature has significant effect on the miscibility of PVA/PEG polymer blends. Scientifically, simple (PVA / PEG) blends and unblends have been defined by the use of (FTIR).
