摘　　要：用4-(4-羟苯基)二氮杂萘酮(DHPZ)、3,3′-二磺酸钠-4,4′-(4-氟苯甲酰基)苯(SDFKK)、2,6-二氯苯腈(DCBN)以及4,4′-(4-氟苯甲酰基)苯(DFKK),通过缩合共聚反应成功合成了一系列不同磺化度、高分子量的磺化聚芳醚腈酮酮(SPPENKKs)。利用红外光谱(FT-IR)与核磁共振谱图(1H-NMR)证明了聚合物分子结构,利用热重分析仪(TGA)研究了氢型聚合物膜的耐热性能。以N-甲基吡咯烷酮为溶剂,用溶液涂敷法成功制备了具有良好韧性的SPPENKKs均质膜。利用乌氏粘度计测定聚合物的粘度,并研究了不同磺化度的聚合物膜的溶解性能、保水能力、热稳定性能、质子传导率等性能。Sulfonated poly（phthalazinone ether nitrile ketone ketone）s copolymers（SPPENKKs） are synthe- sized in high molecular weight via direct polycondensation from SDFKK, DFKK, 2,6-dicholobenzonitrile（DCBN） and DHPZ. FT-IR and ^1H-NMR scattering are used to characterize the structures of SPPENKKs. TGA is used to study the thermal properties of these eopolymers. Tough films are obtained by solution casting method with N-methylpyrro- lidone. The properties of these membranes is studied in detail, which include solubility, water uptake, swelling ratio, oxidative resistance, hydrolysis resistance, ion exchange capacity and proton conductivity,etc.
