摘要

合成了三种含酯基和三种含醚键的炔单体，通过核磁共振氢谱(1H NMR)、红外光谱(FT-IR)、质谱(MS)、液相色谱(LC)对其结构进行了表征。用这六种炔单体与叠氮单体反应制备了一系列新型聚三唑酯树脂(PTAE)和聚三唑醚树脂(PTAO)。利用差示扫描量热分析(DSC)、FT-IR、动态力学热分析(DMA)、力学试验机和热失重分析(TGA)表征了树脂的固化行为、固化树脂的力学性能、耐热性和热稳定性。结果表明PTAE和PTAO树脂易溶于有机溶剂，可低温(60℃)固化，固化树脂的弯曲强度超过了100 MPa，可达158 MPa，玻璃化转变温度(T g)超过180℃，高者达251℃，热分解温度可达360℃。

Abstract

Three kinds of alkyne monomers with ester groups and three kinds of alkyne monomers with ether groups were synthesized

and characterized by nuclear magnetic resonance spectroscopy(1H NMR)

fourier transform infrared spectroscopy(FT-IR)

mass spectrometry (MS) and liquid chromatography (LC). Three poly(triazole ester) resins (PTAEs) and three poly(triazole ether) resins (PTAOs) were prepared from these alkyne monomers and polyfunctional azide monomers. The curing behavior

mechanical properties

heat resistance and thermal stability of the resins were characterized by differential scanning calorimetry (DSC)

FT-IR

dynamic mechanical thermal analysis (DMA)

mechanical tests

and thermogravimetric analysis(TGA). The results show that PTAE and PTAO resins can be dissolved in common organic solvents and can be cured at low temperature (60℃). The flexural strength of cured resins exceeds 100 MPa

and the highest 158 MPa. The glass transition temperature (T g) of cured resins exceeds 180℃

and the highest 251℃. The thermal decomposition temperature(T d5) exceeds 300℃

and the highest 360℃. The mechanical properties

heat resistance and thermal stability of the cured PTAO resins are higher than those of the cured PTAE resins.
