| 摘 要： | 通过三步反应合成新的含氟双酚单体3,4-二氟苯基对苯二酚，由该含氟双酚单体、4-氟苯基对苯二酚、邻苯基对苯二酚分别与4,4′-二氟二苯酮、4,4′-二氯二苯砜经亲核缩聚反应，制备了一系列新型聚芳醚酮和聚芳醚砜。采用 FT-IR、DSC、TGA及XRD手段等对聚合物的结构和性能进行了表征和研究，结果表明：合成的聚芳醚酮和聚芳醚砜具有优异的耐热性能，玻璃化转变温度分别在150~159 ℃和177~196 ℃之间，氮气中5 %热失重温度分别在527 ℃和507 ℃以上。合成的聚芳醚酮和聚芳醚砜具有良好的溶解性，室温下能溶解在N-甲基吡咯烷酮、二甲基乙酰胺、氯仿等有机溶剂中。

| Abstract: | A new bisphenol monomer (3,4-difluoro)phenylhydroquinone (DFPHQ) was obtrained with a three-step synthesis.A series of fluorine-containing poly (aryl ether ketone)s (FPAEK) and poly (aryl ether sulfone) s (FPAEF) were prepared from DFPHQ and 4,4'-diflourodiphenylketone or bis-(4-chlorophenyl) sulfone via nucelophilic aromatic substitution polycondensation.The structures of the monomers and polymers were confirmed by ~1H-NMR and FT-IR,and the properties of FPAEK and FPAEF were studied using DSC,TGA,XRD,etc.I... |
