摘要註:	本研究以光學顯微鏡(OM) 、掃描式電子顯微鏡(SEM) 以及微分掃描熱卡計(DSC)來觀察生物可分解性共聚酯(Poly(butylene adipate-co-butylene terephthalate) (P(BA-co-BT), Ecoflex○R))與聚雙酚A羥基醚(Poly hydroxyl ether of bisphenol-A (Phenoxy))摻合系統之相型態及熱行為，並利用傅立葉紅外線光譜儀(FT-IR)、微分掃描熱卡計(DSC)、液態核磁共振儀(NMR)及原子力顯微鏡(AFM)來佐證此摻合系統經過熱處理後所發生的交酯化反應。為了瞭解共聚酯P(BA-co-BT)與Phenoxy摻合系統之特性，研究中亦探討均聚合物摻合系統－Phenoxy/poly(1,4-butylene adipate)(PBA)及Phenoxy/poly(1,4-butylene terephthalate)(PBT)之相型態、熱行為及交酯化反應機制。由相型態及熱行為分析結果，Phenoxy/P(BA-co-BT)及Phenoxy/PBA摻合系統皆呈現均勻相及單一玻璃轉移溫度之相容系統，且Tg會隨Phenoxy組成比例改變。以Florry Huggins equcation計算Phenoxy/P(BA-co-BT)分子作用力參數χ12值為χ12=－0.14，而Phenoxy/PBA分子作用力參數χ12值為χ12=－0.336。另外，Phenoxy/PBT摻合系統則呈現非均勻相及分別出現在phenoxy rich-phase和 PBT rich-phase區域的玻璃轉移溫度之相分離系統。研究中再以260及280℃熱處理Phenoxy/Ecoflex、Phenoxy/PBA、Phenoxy/PBT各組成比例摻合系統，其結果皆呈現均一相，且玻璃轉移溫度皆有增加趨勢，表示摻合系統經過熱處理後，產生特殊之化學交互作用力。此外，FTIR分析結果也顯示Ecoflex中PBA的C=O(1735cm-1)與PBT的C=O(1716cm-1)經過熱處理會接會位移至1720cm-1，表示摻合系統經過熱處理後，產生特殊之化學交互作用力，使其C=O的peak產生位移。Phenoxy/Ecoflex、Phenoxy/PBA、Phenoxy/PBT各組成比例摻合系統於260及280℃熱處理後會產生特殊化學交互作用力－交酯化反應中的醇解反應，以Phenoxy/Ecoflex而言，此反應機制為Phenoxy的OH基會去分別攻擊PBA與PBT之C=O前端的脂肪族，並且會與Ecoflex接枝。並且，以NMR分析結果發現Phenoxy/Ecoflex=5/5摻合比例之系統，於280℃熱處理前後並沒有發現化學位移，其原因為摻合系統於熱處理前後的分子間結構是相似的，所以未導致有明顯之化學位移。AFM分析Phenoxy/Ecoflex重量比為5/5之摻合系統，結果也顯示其粗糙度會隨熱處理時間增加而改變，表示此摻合系統經過熱處理後，因化學交互作用力而使粗糙度發生改變。再以DSC觀察摻合系統經高溫循環熱處理後的結晶溫度變化情形，發現結晶溫度會受循環次數和循環熱處理時間影響，以此更加證明經過熱處理後各摻合系統會產生化學交互作用力，而此化學交互作用力及為交酯化反應。 Miscibility, Thermal behavior and Tranesterification of the Poly(butylene adipate-co-butylene terephthalate)/Phenoxy (P(BA-co-BT)/Phenoxy) blends were investigated by differential scanning calorimetry (DSC), optical microscopy (OM), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and atomic force microscopy, (AFM). In order to understand properties of P(BA-co-BT)/Phenoxy blends, miscibility, thermal behavior, and transesterification of the homopolymers blends, Phenoxy/poly(1,4-butylene adipate) (Phenoxy/PBA) and Phenoxy/poly(1,4-butylene terephthalate) (Phenoxy/PBT) blends were also investigated in the study. The result of phase morphology and thermal analysis revealed that the Phenoxy/P(BA-co-BT) and Phenoxy/PBA exhibited a homogeneous phase and a composition-dependent glass transition temperature (Tg), indicating the blends were miscible. In the Phenoxy/P(BA-co-BT) blends, the interaction parameter χ12 was -0.14, and the interaction parameter χ12 was -0.336 in the Phenoxy/PBA blends. The Phenoxy/PBT blends exhibited a heterogeneous phase and composition-independent glass transition temperature (Tg), indicating the blend was immiscible. Moreover, the result of thermal analysis revealed that a homogeneous phase and the glass transition temperature (Tg) increased in the Phenoxy/P(BA-co-BT), Phenoxy/PBA and Phenoxy/PBT blends when it was heated at 260℃. Apparently, there was a chemical interaction in the Phenoxy/P(BA-co-BT)、Phenoxy/PBA and Phenoxy/PBT blends after heat treatment. Also, the result of AFM revealed chemical interaction in the Phenoxy/P(BA-co-BT) blends. The crystallization temperature of the blend subjected to cyclic heating/cooling treatment is influenced by the total annealing time. Some transesterification reactions might occur in the Phenoxy/P(BA-co-BT) blends. Furthermore, the result of FT-IR revealed chemical interaction in the Phenoxy/P(BA-co-BT)、Phenoxy/PBA and Phenoxy/PBT blends. In the study, a special dual transesterification was proved in the Phenoxy/P(BA-co-BT)、Phenoxy/PBA and Phenoxy/PBT blends. Finally, the mechanisms of transesterification in the Phenoxy/P(BA-co-BT), Phenoxy/PBA and Phenoxy/PBT blends were suggested in the study.
