摘要： 用亲核取代路线合成了含亚联苯结构的新型聚醚醚酮酮(联苯PEEKK),并对其基本性能进行了测定。结果表明,联苯PEEKK的Tm比聚醚醚酮(PEEK)高77℃,其Tg比PEEK的高41℃,且保持了良好的力学性能。本文还对联苯PEEKK的晶体结构进行了初步探讨。

Abstract: Poly(aryl ether ketones) are used as matrix resin in advanced high-performancecomposites because of their excellent properties. In this paper, diphenol-PEEKKhas been prepared by copolycondensation of 4,4'-diphenol and 1,4-bis(p-fluorobenzoyl)benzene in the precence of diphenylsulphone. The general properties are studied by IR, DSC, TGA,etc.. The service temperature of diphenol-PEEKKis higher than that of PEEK, and the mechanical properties are as good as those of PEEK. The crystal structure of this polymer is also studied.

Key words: Poly(ether ether ketone ketone), 4,4'-Diphenol, 1,4-bis(p-fluorobenzoyl)benzene
