Copoly(ether imide)s were obtained from diamine containing phthalazone and p-phenylenediamine or m-phenylenediamine with BPA dianhydride by "one step" polycondensation. The copolymers were studied by IR、DSC、mechanical property and solubility measurements. The results show that the T_gs of the copolymers are 8~35℃ higher than that of Ultem and increase with increase in phthalazone in the polymer's backbone. The copolymers have good solubility and a little increased tensile strengths.
