Abstract Copoly(aryl ester)s containing phthalazinone moieties (PPAR-D) were synthesized by interfacial polymerization of 2,2-bis(4-hydroxyphenyl)-propane and 4-(4-hydroxyphenyl)-2,3-phthalazin-1-one with isophthaloyl dichloride. The effect of organic solvent, the type of the catalyst, the type and amount of the alkali, the molar ratio of two bisphenol monomer and Isophthaloyl chloride on the intrinsic viscosity of PPAR-D were investigated. The intrinsic viscosity of PPAR-D reached 0.35 dL/g, and decreased with the increase of DHPZ content in monomers. Chemical structure of PPAR-D was characterized with FT-IR and 1H-NMR. The results indicate that PPAR-D was successfully obtained. The properties of PPAR-D were characterized by TGA, solubility, and intrinsic viscosity. The results show that PPAR-D exhibited good thermal stability. PPAR-D have good solubility in chloroform and dimethyl sulfoxide, N,N-dimethylformamide, N-methylpyrrolidone and other common organic solvents
