PP-NR blends with different loading of NR (0, 10, 20, 30, 40, and 50 wt/wt %) were prepared via melt mixing technique. NR, depending on its loading, actuates dramatic phase … Webbrheological behavior according to the flow conditions. The results include a nonlinear response at high shear rates, as well as substantial differences between shear and extensional flow. Plotting the viscosity η of linear and related polymers versus shear rate ()γ produces a characteristic flow curve (Figure 1).
