الوصف: The phase behavior and miscibility of poly(e-caprolactone) (PCL)/polycarbonate (PC) blends have been investigated with DSC, cloud-point measurement, TGA, STIR, NMR, and SANS. Thermal analysis results indicated that the PCL-rich blends are semicrystalline/semicrystalline at room temperature. At about 30% PC incorporation, the PCL crystallinity showed a marked reduction, whereas the PC crystallinity approached a maximum. The composition dependence of T g exhibited a discontinuity (cusp) and was critically analyzed using the classical equations of Gordon-Taylor and Fox and the free volume theory of Braun-Kovaca
