Rheology Investigation of Low Molecular Weight Poly(mthyl methacrylate)/Polystyrene Blends

Small amplitude oscillatory shear rheology was employed to investigate the linear viscoelastic behavior of low molecular weight polystyrene/poly (methylmethacrylate) (PS/PMMA) blends. The frequency sweep tests of the blends showed a distinct and particular behavior below and above the cloud point. The time sweep of the blends was quite dependent on the blend composition. The results also showed that the rheological behavior of each constituent is among the influential parameters affecting the blend rheology
