Characterization of Polymer Blends Miscibility, Morphology, and Interfaces, First Edition. 

ultimately, the properties of a polymer blend will depend on the final morphology, various research groups have recently undertaken extensive studies of the miscibility and phase behavior of polymer blends. In practice, the physical properties of interest are found either by miscible pairs or by a heterogeneous system, depending on the type of application. Generally, polymer blends can be completely miscible, partially miscible or immiscible, depending on the value of AG [4]. 

For miscibility (binary blend), the following two conditions must be satisfied the first condition AG 0 and the second condition
