摘要:采用二聚脂肪酸(DFA)、乙二胺(EAH)和对甲苯基磺酰异氰酸酯(PTSI)为原料,合成了主链上带有互补氢键基团的酰胺低聚物,最终形成网状氢键超分子聚合物DFA-EAH和DFA-EAH-PTSI。利用红外光谱(FT-IR)、核磁共振氢谱(1H-NMR)、凝胶渗透色谱(GPC)表征了产物结构;通过差示扫描量热分析(DSC)、动态热机械分析(DMA)的损耗角正切和热重分析(TGA)对合成产物的热性能进行了表征。结果表明:产物在常温下表现为弹性体性质,熔点低、热稳定性和力学性能良好。
Hydrogen-bonding supramolecular network polymers DFA-EAH and DFA-EAH-PTSI were assembled by amide oligomers which were synthesized from dimeric fatty acid(DFA),ethylenediamine(EAH) and p-toluenesulfonyl isocyanate(PTSI).The structures of polymers were characterized with infrared spectrascopy(FT-IR),proton NMR(1H-NMR) spectrascopy and gel permeation chromatography(GPC).Thermal properties were investigated with differential scanning calorimetly(DSC),loss angle tangent of dynamic thermal mechanical analysis(DMA) and thermogravimetric analysis(TGA).Results show that the products have low melting temperature and good thermal stability,and behave like elastomers at room temperature.Tensile tests show that the products have good mechanical properties.
