AB  - Partially miscible polymer blends are characterised by the occurrence of homogeneous or multi-phase microstructures depending on the prevailing conditions of composition, temperature, pressure and flow. The capability to deliberately shift their phase diagram through the application of flow is of particular interest in manufacturing, since it opens up a range of opportunities for the generation of products with 'controllably inhomogeneous' microstructure through 'smart processing'. Key in this, is the ability to quantify the effect of flow on the phase diagram. This work presents a theoretical analysis of this problem along with supporting experimental evidence. This analysis is in qualitative agreement with experimental evidence of shear-induced mixing in SAN/PMMA blends. The presented analysis seems to indicate that by determining the compositional dependence of blend viscosity one may be able to predict the direction in which shear might shift the phase diagram.
