摘要

一系列的聚對苯二甲酸乙二酯與聚癸二酸乙酯之共聚物聚合成出來，首先使用NMR與FTIR及IV測定來鑑定其化學結構，接著藉由DSC、TGA、DMA、WXRD 及拉伸測試進行熱及機械性質分析，透過酵素分解實驗評估生物可降解性，實驗結果表明，以癸二酸取代對苯二甲酸時，聚合物之生物可降解性能明顯提升，當共聚物中癸二酸莫耳數等於對苯二甲酸時，共聚物具有優異的綜合機械性質，本研究成功以生質癸二酸製備出具有生物降解性能之高性能彈性體，為新型環保熱塑性彈性體之候選材料之一。

A series of poly(ethylene terephthalate-co-ethylene sebacate)s (PESeT)s were synthesized. First of all, the chemical structures of these prepared copolymers were characterized by NMR, FTIR and IV measurements. Then, the Tm, Td, Tg, crystalline state and mechanical properties of them were analyzed via DSC, TGA, DMA, WXRD and tensile test, respectively. Through the in vitro enzyme degradation test, the biodegradability of the polymers were estimated. The result shows that the biodegradability of the PESe better than PET obviously. While the mole ratio of SeA equal to that of TPA, the PESeTs possess great integral mechanical properties. In this work, the biodegradable high performance elastomers were produced from the biobased sebacic acid. These PESeTs are one of the candidate materials for a novel environmentally friendly thermoplastic elastomer.
