Two aromatic polysulfones, poly(PhC-co-SDA)-2 and poly(TPhC-co-SDA)-2, were synthesized by interfacial polycondensation of phthaoyl chloride(PhC) and terephthaloyl chloride(TPhC) with P, P'-sulfonyldianiline(SDA), respectively. The properties of the aromatic polysulfones synthesized were as follows : inherent viscosity, $0.32{\sim}0.35dL/g$:glass transition temperature, $220{\sim}240^{\circ}C$:tensile strength, $308{\sim}336Kg/cm^2$:and 5% weight loss temperature by TGA thermogram in the air, $500{\sim}530^{\circ}C$. As the result, thermal properties of the synthesized copolymers proved to be excellent.
