摘要本文从三种新芳醚单体4,4’-双(1-萘氧基)二苯砜(DNODPS)、4,4’-双(1-萘氧基)二苯甲酮(DNOBPN)、9,9-二[(4-苯氧基)苯基]芴（BPOPF）出发，通过亲电路线与各种芳二酰氯进行缩聚反应合成了两类新型可溶性聚芳醚酮。1.以4,4’-双(1-萘氧基)二苯砜(DNODPS)、4,4’-双(1-萘氧基)二苯甲酮(DNOBPN)为醚单体，分别与间-苯二甲酰氯(IPC)、对-苯二甲酰氯(TPC)、1,4-萘二甲酰氯进行低温缩聚反应,合成了一系列主链含1,4-萘结构聚芳醚酮树脂,并用FT-IR、DSC、TG、XRD、GPC、拉伸等分析技术对聚合物进行表征和性能测试。研究结果表明，将1,4-萘结构引入到大分子链中显著提高了聚合物的溶解性，使聚合物可溶于NMP、DMAc、氯仿等多种强极性有机溶剂，且聚合物有很高玻璃化转变温度(Tg)(200-254℃)和热分解温度(Td)(487-523℃)。2.9,9-二[(4-苯氧基)苯基]芴为芳醚单体，分别与间-苯二甲酰氯(IPC)、对-苯二甲酰氯(TPC)、1,4-萘二酰氯、4,4’-联苯二甲酰氯和2,6-萘二甲酰氯进行低温缩聚反应,合成了一系列含芴侧基的聚芳醚酮树脂,并用FT-IR、DSC、TG、XRD、GPC、拉伸等分析技术对聚合物进行表征和性能测试。研究结果表明，将芴结构引入到大分子链中显著提高了聚合物的溶解性，使聚合物可溶于NMP、DMAc、氯仿等多种强极性有机溶剂，且聚合物有很高玻璃化转变温度(Tg)(228-300℃)和热分解温度(Td)(491-542℃)。关键词：4,4’-双(1-萘氧基)二苯砜(DNODPS)；4,4’-双(1-萘氧基)二苯甲酮(DNOBPN)；9,9-二[(4-苯氧基)苯基]芴；聚芳醚酮；聚芳醚酮酮；亲电缩聚ABSTRACTFromthreearomaticethermonomers：4,4-bis(-naphthoxy)phenylsulfone(DNODPS),4,4-bis(-naphthoxy)benzophenone(DNOBPN),9,9-bis(4-phenoxyphen-yl)fluorene(BPOPF),wesynthesizedtwonewtypesofsolublepoly(aryletherketone)sbyelectrophilicpolycondensationwithvariousaromaticdiaciddichlorides.Aseriesofnovelpoly(aryletherketone)swith1,4’-naphthalenemoietieswerepreparedfrom4,4-bis(-naphthoxy)diphenylsulfoneand4,4-bis(-naphthoxy)benzophenone(DNOBPN)byelectrophilicpolycondensationwithisophthaloylchloride,terephthaloylchlorideand1,4’-naphthalenedicarboxylicaciddichloride.ThestructuresandpropertiesofthepolymerswereinvestigatedbyFT-IR,TG,DSC,XRD,GPCetc.TheresultsshowedthatthepolymersweresolubleincommonorganicsolventssuchasN-methyl-pyrrolidone(NMP),N,N-dimeth-ylacetamide(DMAc),andCHCl3atroomtemperature.ThepolymershadnotonlyhighTgsof200-254℃,butalsohighTdsof487-523℃.Aseriesofnovelpoly(aryletherketone)swithpendantfluorenegroupswerepreparedfrom9,9-bis(4-phenoxylphenyl)fluorenewithvariousaromaticdiaciddichloridessuchasisophthaloylchloride,terephthaloylchloride,1,4’-naphthalenedicarboxylicaciddichloridebyelectrophilicpolycondensation.ThestructuresandpropertiesofthepolymerswereinvestigatedbyFT-IR,TG,DSC,XRD,GPCetc.Theresultsshowedthatthepoly
