AB -  The use of polymer mixtures to achieve an economic or property ad­ vantage is not new. Mixtures of rubbers have been used for many years in the tire industry, impact-modified polystyrene in which a dispersed rubber phase is incorporated to improve ductility and impact resistance through craze formation is commonplace, and several commercially significant thermoplastic blends, notably poly(phenylene oxide)/poly­ styrene, ABS/polycarbonate, and PVC/PMMA are known. What is perhaps new is the growing awareness among the scientific and engineer­ ing communities that many more· potentially interesting polymer mix­ tures are possible, and that commercially useful materials can be devel­ oped by simply melt mixing already existing ones. Polymer blends can be characterize d by their phase behavior as being either miscible or immiscible. Immiscible blends show multiple amorphous tially pure blend component, whereas the phases of partially immiscible phases. Each phase of a completely immiscible blend contains an essen­ blends may contain some of each material in the blend. There are also blends that are completely miscible and have only one amorphous phase. The mechanical, thermal, rheological, and other properties of a polymer blend depend strongly on its state of miscibility. Conceptually, this state is determined by the thermodynamics
