초록
다양한 함량의 테레프탈산, 에틸렌글리콜, 1,4-싸이클로헥산 디메탄올, 이소소바이드로 구성된 일련의 바이오 기반 삼원 공중합체들의 특성을 1H NMR과 13C NMR을 이용하여 연구하였다. NMR 분석 결과 모두 랜덤한 미세 구조를 가졌고 시퀀스 분포는 이소소바이드의 함량에 따라 영향을 받았다. 시차주사열량계(DSC) 데이터로부터 유리전이온도는 주로 이소소바이드 함량이 증가함에 따라 증가하는 것을 알 수 있었다. 또한 확장된 Fox 식을 이용하여 각 성분의 함량에 따른 삼원공중합체의 유리전이 온도를 예측하고자 하였다.
Characterization of a series of bio-based terpolymers containing various amounts of ethylene glycol, 1,4-cyclohexylene dimethanol, and isosorbide units were studied by 1H NMR and 13C NMR. The NMR results revealed that they had all random microstructures and that their sequence distribution was affected by the content of isosorbide. From DSC data for the terpolymer series investigated, it was observed that the glass transition temperature increased mainly as the content of isosorbide increased. The glass transition temperatures of terpolymers were estimated from the composition by extended Fox equation.
