Abstract

Model immiscible blends were tested for morphology and rheological properties. With planar compression comes a loss of co-continuity. Transient viscosity overshoot is larger with the blend than with either component. Storage modulus is affected by the blend morphology at low shear rates. Shear viscosity at high shear rates is 30 percent lower than either component. Normal stress and viscosity are both larger than the mean between the phases, and die swell with the blend is larger than with either component.
