摘要/Abstract

摘要： 采用亲核取代反应，用间苯三酚与4，4′-二氟二苯酮反应合成一种可用于制备超支化聚芳醚酮的B₃型单体，由MS，IR和¹H NMR等方法对单体进行表征.进一步采用A₂+B₃法制备超支化聚醚醚酮，研究了端基对其热性能、溶液粘度特性的影响.结果表明，羟基封端聚合物玻璃化转变温度、比浓对数粘度高于氟封端聚合物，热稳定性低于氟封端聚合物.

关键词: B₃型单体, 超支化聚醚醚酮, 羟基封端, 氟封端

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
