Compatibility of Polyethersulfone/Polycarbonate Blends

Abstract

polycarbonate (PC), polyethersulfone (PES) and a multi-block random copolymer of PES and PC were blended. It was found that the interfacial adhesion was enhanced, the size of the dispersed phase was reduced and PES and PC formed an interlocking structure with the copolymer, which suggest the addition of the compatibizer may improved the miscibility between PES and PC, and result in the improvement of the mechanical properties of the blends. The compatibility behavior of PES with PC was examined using differential scanning calorimeter (DSC), scanning electron microscope (SEM) and SAXS.
