摘要: 聚醚醚酮酮(PEEK)是聚芳醚酮典型品种之一。由于它具有热固性塑料的耐热性,化学稳定性,又具有热塑性塑料的成型加工性,尤其是它的耐高温特性,使它在电子电器,机械仪表,交通运输宇航等领域得到应用。PEEK的Tg=143℃,Tm=334℃。我们用联苯二酚代替对苯二酚,同时加入间位的二氟化物。得到Tg=169℃,Tm=339℃的含联苯的聚醚醚酮酮。它有可能成为使用温度高于PEEK而加工条件与PEEK基本相同的耐高温树脂。

Abstract: A kind of polyetheretherketone ketone has been prepared by copolyeondensation of 4,4′-diphenol, 1,3-bis (4-fluorobenzoyl) benzene and 1,4-bis (4-fluorobenzoyl) benzene with alkali metal carbonates at 310~320℃ using diphenylsulphone as solvent. The copolymer has Tg=169℃,Tm=339℃, 2.5% weight loss at 555℃;tensile strength 68.5MPa and tensile modulus 0.915GPa.
