摘要： 聚芳醚酮是一种新型热塑性耐高温高分子材料,具有优异的力学性能、电性能、抗辐射性能等,特别适合作高性能复合材料的基质及超级工程塑料,关于聚芳醚酮已有多篇文章报道,而基于C-N偶合反应合成的聚芳醚酮报道甚少[1],我们曾报道含氮杂环聚醚酮酮PPEKK的合成[2].本文以1,4-二(4-氯代苯甲酰基)苯,4,4′-二氟二苯酮及4-(4-羟基苯基)-2,3-二氮杂 萘-1-酮为原料,合成了主链中含有C—N键的新型含氮杂环聚芳醚酮三元共聚物 (PPEKEKK),对共聚物的结构和性能进行了表征.

Abstract: A novel poly(aryletherketone) copolymer containing phthalazinone moiety was prepared by nucleophilic substitution reaction of 4-(4-hydroxyphenyl)(2H) phthalazin1one with bis-1,4-(4-chlorobenzoyl) benzene(BCBB) and 4,4'-difluorobenzophenone(DFPK). The copolymer has been studied by FTIR, DSC, TGA and X-ray diffractometry. It is an amorphous plastics with Tg=245～254℃ and good thermal stability, and the Tgs of the copolymer were increased with decreasing of molar ratio of BCBB to DFPK. The copolymer is soluble in aprotic dipolar solvents.

Key words: poly(aryletherketone), hetero cyclic copolymer, property
