【摘要】 以 4,4′ 二氟二苯酮和 4 (4 羟基苯基 ) 2 ,3 二氮杂萘 1 酮经亲核取代逐步聚合制得含二氮杂萘酮结构的聚芳醚酮低聚物 ,再与环氧氯丙烷反应制得了所需分子量的含环氧端基的聚芳醚酮 (E PPEK) .用FT IR和1H NMR表征了分子链结构 ,并测定了聚合物的玻璃化转变温度Tg 和溶解性 .更多还原

【Abstract】 A novel epoxy\|terminated polyaryletherketone(E\|PPEK)was synthesized by the reaction of epichlorohydrin with PPEK oligomer prepared by nucleophilic substitution of 4,4′ \|difluorobenzophenone(DFK) with 4\|(4\|hydroxyphenyl)\| 2,3 \|phthalazine\|1\|one.E\|PPEK samples were characterized by FT\|IR and 1H\|NMR spectra,and their solubility was also determied.更多还原
