中文摘要
本研究最主要利用微分掃瞄熱卡計（DSC）、偏光顯微鏡（POM）、與掃瞄式電子顯微鏡（SEM）、傅利葉紅外線光譜儀(FTIR)來觀察、鑑定poly（ethylene terephthalate）/poly（trimethylene terephthalate）/poly（butylene terephthalate）/poly（ether imide）（PET/PTT/PBT/PEI）與poly（trimethylene terephthalate）/polycarbonate（PTT/PC）摻合系統之相型態及其相容性。在PET/PTT/PBT/PEI四成分摻合系統中，分別使用熔融摻合與共沉澱法來製備試樣。當用共沉澱法製備試樣，則可發現試樣有著單一的Tg，而SEM觀察結果為均一的相型態。故於不定型態時， PET/PTT/PBT/PEI四成分高分子摻合系統為一相容的系統。在PTT/PC系統中，溶劑摻合製備之試樣於所有組成與50/50熔融摻合之試樣熱分析結果都呈現兩個Tg，且POM的觀察也都顯示存在相分離區域，故此系統應為一相分離之系統。而摻合物於260℃停留後，可發現會由兩Tg隨停留時間增加逐漸轉變為單一Tg，且由高溫降溫時結晶的溫度亦會受總循環熱處理時間與循環次數影響，FTIR的測試結果亦發現吸收峰之shoulder有著可能因熱處理後分子間作用力不同而有的些許位移，因此推測PTT/PC摻合系統於高溫處理後之改變有可能為交酯化所造成。

Abstract
This study investigates the morphology and the miscibility of the blends containing poly (ethylene terephthalate) (PET), poly (trimethylene terephthalate) (PTT), poly (butylene terephthalate) (PBT), poly (ether imide) (PEI) and polycarbonate (PC) using differential scanning calorimeter (DSC), polarizing optical microscope (POM), scanning electron microscope (SEM) and Fourier transform infrared spectrometer (FTIR). Both hot-melt blending and solvent blending techiques were performed in preparing the PET/PTT/PBT/PEI mixtures. If the mixture samples were prepared by solvent coprecipitation, a single Tg and the homogeneous morphology indeed exist in the PET/PTT/PBT/PEI mixtures. It was believed that in amorphous state this blending system revealed a completely miscibility, in the other words, a miscible system. In addition, for PTT/PC blends, two individual Tg values and POM results revealed phase separation in the blends which implied immisicibility. When PTT/PC blends were annealed at high temperature, transesterficition between PTT and PC molecules may be generated. Original two Tgs were transferred to one and the crystallizing temperature after cyclic heat treatment also effected by the total annealed times. At last a shoulder shift phenomenon of FTIR absorbed peak implied that there was the interaction in this blending system.
