摘　　要：以对氯硝基苯和双酚S为原料经缩合和铁粉还原合成了聚酰亚胺二胺单体4,4’-双(4-氨基苯氧基)二苯基砜(P-BAPS);考查了工艺条件对产物收率的影响,并利用红外光谱(IR)、差式扫描量热仪(DSC)对其及聚合物进行表征。结果表明:当n(硝基物)∶n(铁粉)=1∶6.75,80℃下反应6h,产物收率可达87.70%;相应聚酰亚胺薄膜拉伸强度为73.2MPa,断裂伸长率7.3%。A novel monomer diethylenetriamine of polyimide 4,4＇-Bis（4-aminophenoxy）phenyl sulfone（P-BAPS） was synthesized by condensation and reduction.Factors including the molar ratio of raw,reaction temperature and reaction time were investigated,and the production was characterized by FT-IR,DSC.Base on research,the yield of production was 87.70%,when the molar ratio of nitro-compound and iron was 1：6.75 and reaction temperature at 80 ℃ for 6 h.The tensile strengh of polyimide was 73.2 MPa and breaking elongation was 1.7%
