摘要
聚醚醚酮（ＰＥＥＫ）自工业化以来［１］，由于其优异的性能已在机械、航天等领域得到广泛应用．各种聚芳醚酮类聚合物相继被开发出来．但以亲电缩聚路线制备聚醚醚酮醚酮（ＰＥＥＫＥＫ）的报道较少［２］．本文以二苯醚和４－氟苯甲酰氯为主要反应试剂，采取付氏酰基化...
Bis(fluorobenzoyl)diphenyl ether was prepared and polycondensed with hydroquinone to give a PEEKEK. The polymer has been characterized by IR, DSC, TGA and WAXD methods. It has the same crystal structure as PEEK and also a good thermal stability. The Tg, Tm and thermal decomposition temperatures(weight loss=5%) were found to be 134 , 315 and 510 , respectively.
