Abstract: Poly (ether ether ketone) (PEEK), a high-temperature resistant thermoplastic resin, has been used in a lot of fields because of its excellent properites.With the development of high technology, the resins having higher service temperature are required.Aseries of terpolymers(DPEEKs) have been prepared by copolycondensation of hydroquinone, 4,4'-diphenol and 4,4'difluorobenzophenone with alkali metal carbonate at 320-350℃ using diphenylsulphone as solvent for the reaction.The Ts of a DPEEKby the nucleophilic substitution route is higher than that of a PEEK.The relationships between Ts, Tm and the molar ratio of 4,4'-diphenol are studied by a differential scanning calorimeter.The DPEEKs possess higher service temperatures than PEEK, and their mechanical properties are as good as those of PEEK.

Key words: Poly (ether ether ketone), 4, 4'-Diphenol, Poly(aryl ether ketone)
