Abstract: Hyperbranched poly（ether ether ketone）were prepared by polymerization of hydroquinone（A₂）and 1，3，5-tris[4-（4-fluorobenzoyl）phenoxy]benzene（B₃）.The gelatin formation of hyperbranched poly（ether ether ketone）was effectively avoided.Hydroxyl-terminated （HPEEK-OH）and fluoro-terminated （HPEEK-F）hyperbranched poly（ether ether ketone）were prepared from the mixture of hydroquinone （A₂）and 1，3，5-tris-[4-（4-fluorobenzoyl）phenoxy]benzene （B₃）with different A₂/B₃mass ratios.The structure of B₃ monomer was confirmed by mean of MS，¹H NMR，IR.The glass transition temperatures of HPEEK-F and HPEEK-OH are 114℃ and 162℃ respectively.Thermal stability of HPEEK-F is higher than that of HPEEK-OH．

Key words: B₃ monomer, hyperbranched poly（ether ether ketone）, hydroxyl-terminated, fluoro-terminated
