摘要：
The miscibility behavior of poly(methylmethacrylate)/poly(styrene-co-acrylonitrile) (PMMA/SAN) blends with changes in blend ratio and acrylonitrile content of SAN was investigated by laser light scattering. The results show a miscibility window in the temperature versus copolymer composition plane. The phase morphology was observed over the whole copolymer composition and temperature area by light microscopy. A highly interconnected two-phase structure which occurs just above the lower critical solution temperature can also be found at room temperature in a certain region just outside the composition of the miscibility window. The differential scanning calorimetry trace of miscible systems displays a broadening at high PMMA contents in the blend.
