Compatibilizing Modification of Polyethersulfone/Polycarbonate Blend

Article Preview

Abstract:

Double block copolymers of polyethersulfone (PES)/polycarbonate (PC) were used as a compatibilizer for a blend of PES/PC. The morphology, thermal properties, mechanical properties, etc. of the resulting ternary blend systems were investigated. The addition of the compatibizer improved the compatibility between PES and PC. It was found that the interfacial adhesion was enhanced; the size of the dispersed phase was reduced. This resulted in an improvement of elongation at break and tenacity of PES/PC blends, while the tensile modulus slightly increased, and tensile strength was almost constant.
