Abstract
Blends of a poly(ether sulfone) (PES) and a polycarbonate (PC) were pr epared by melt-mixing and were studied by tensile tests, differential scanning calorimetry, dynamic mechanical analysis, density measurement s and transmission electron microscopy (TEM). The blends were found to be two-phase systems and an interfacial layer was presumed to be form ed between two phases, which was verified by TEM. A synergism of elong ation at break and tensile modulus was shown in PES/PC blends. The eff ects of the crosshead speed on the mechanical properties were discusse d for blends with different PES/PC weight ratios.
