dc.description.abstract Methylene dianiline(MDA)와 trimellitic anhydride (TMA)를 반응시켜 diacid diimide (DID)를 합성하고 이를 과량의 ethyleneglycol과 반응시켜 bishydroxyethylbisimide(BHEI) 중간체를 합성하였다. 다음 dimethylterephthalate와 ethyleneglycol를 에스테르 교환 반응시켜 bishydroxyethyl terephthalate(BHET)중간체를 합성하였고 이를 BHEI와 280℃, 감압(1~3 ㎜Hg)의 용융상태에서 축합 중합하여 polyester-imide를 얻었으며 GPC 및 ^1H-NMR로 분자량 및 공중합체 조성을 구하였다. 생성된 공중합체는 imide단위가 2-10 mole% 함유됨에 따라 PET단독중합체(T_g=78.9℃)보다 내열성(공중합체 T_g=81.9-91.6℃) 이 증가됨을 확인하였다. -
