A series of novel polytriazoleimides were prepared from various aromatic dianhydrides and a new kind of 1,2,3-triazole-containing aromatic diamine synthesized by the Cu (I)-catalyzed 1,3-dipolar cycloaddition reaction in DMAc, and characterized by FT-IR, -NMR, XRD, DSC and TGA techniques. The results show the polytriazoleimides are soluble in most of strong polar solvents and have inherent viscosity
以多种芳族二酐为原料,通过Cu(I)催化的1,3-偶极环加成反应在DMAc中合成一种新型含1,2,3-三唑的芳族二胺,制备了一系列新型聚三唑酰亚胺,并通过FT表征-IR、-NMR、XRD、DSC和TGA技术。结果表明,聚三唑酰亚胺可溶于大多数强极性溶剂,特性粘度值为0.51-0.62 dL/g(DMAc)。聚三唑酰亚胺薄膜在大气中的拉伸强度为 62.3-104.5 MPa,断裂伸长率为 4.0-8.1%,玻璃化转变温度为在 10 MHz 时为 2.47-3.01,这取决于聚合物的结构。聚三唑酰亚胺具有良好的耐酸碱溶液性能。
