| 摘 要： | 用熔融缩聚法合成了一系列聚(丁二酸丁二醇酯丁二酸环己烷二甲醇酯)的无规共聚物。用FT-IR,1H-NMR,DSC,TGA,XRD及水降解测试等方法表征了材料的结构与性能。通过DSC和TGA分析得到产物的熔点虽然较聚丁二酸丁二醇酯(PBS)有所降低,但是热分解温度却得到了提高;XRD测试结果表明,共聚物的晶体结构并没有发生改变;水降解测试结果表明,共聚物较PBS的降解速率有所提高。

| Abstract: | A series of copolyesters of succinic acid-1,4-butanediol/succinic acid-1,4-cycl-ohexanedimethanol were synthesized and characterized by means of Fourier transform infrared spectroscopic(FT-IR),hydrogen nuclear magnetic resonance spectrum(1H-NMR),differential scanning calorimetry(DSC),thermogravimetry analysis(TGA),X-ray diffraction(XRD) and hydrolytic degradation.Though the melting temperature decreased,the copolymers showed the higher thermal decomposition temperature which was justified by TGA.X-ray diffr... |
