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. 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/B3 mass ratios. The structure of B3 monomer was confirmed by mean of MS, 1^ H 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
