This chapter discusses the morphology development of immiscible binary polymer blends. It first describes morphology development in droplet-matrix structures, the dynamics of fibrillar structures and cocontinuous structures. The chapter then considers binary immiscible polymer blends, such systems consist of either dispersed domains in a continuous phase or of two cocontinuous phases. Polymer blends are generally solid at room temperature but they constitute a very viscous emulsion during their processing in the melt. This allows for morphology development during blending and further processing, while the blends are subjected to flow. The chapter also focuses on the morphology development in shear flow, which is the main flow component in many processing, mixing and other operations that involve rotating or moving parts. The polymer blending is industrially used for quite a long time to develop polymeric materials with properties that are a synergistic combination of those of the components.
