Effects of Processing Parameters on Phase Morphology

1 Composition of the Blend The general tendency in uncompatiblized blends is that the droplet size increases as the composition increases up to the onset of co-continuity of the two phases. The driven mechanism accepted is that beyond the concentration of dilution, and particle-itarticle eoalescence dominates the particle breakup process. 

Few authors have investigated the role of the mixer type on phase morphology. We believe that the mixers, although designed differently, can mainly differ in the various types of flow or differing levels of shear. That means their effect is the same as the effect of the flow type and the shear rate they generate. Indeed, as observed by Sundararaj [24], no big differences, in terms of phase morphology, were found between an internal batch mixer [31] and a TSE [32].
