초록

Dianhydride를 메탄올로 에스테르화하고 염소화한 후 diamine과 축중합시켜 poly(amic methylester) (PAME)를 제조하였다. 이렇게 얻은 PAME 및 poly(amic acid) (PAA) 단독중합체 간의 용액블렌드를 행하고 열이미드화로 폴리이미드 블렌드(PIB)를 제조하였다. PAA/PAA 블렌드에서 얻어진 PIB는 하나의 T_g만 가졌으나, PAA/PAME 및 PAME/PAME 블렌드에서 얻어진 PIB는 2개의 T_g를 나타내었다. TGA측정에서 PAA/PAME 및 PAME/PAME 블렌드의 PIB는 PAA/PAA 블렌드에서 얻어진 PIB와 비슷한 열안정성을 나타내었다. PAA/PAME 및 PAME/PAME 블렌드에서 얻어진 PIB의 기계적인 성질이 PAA/PAA 블렌드의 PIB보다 상대적으로 우수하였다.

Poly(amic methylester) (PAME) was synthesized from dianhydride which was esterificated with methanol and then chlorinated with thionyl chloride followed by reaction with diamine. Polyimide blend(PIB) was obtained by thermal imidization of solution blend of poly(amic acid) (PAA) and PAME. PIB obtained by PAA/PAA blend had only one glass transition temperature(T_g), while that obtained by PAA/PAME and PAME/PAME blends exhibited two T_g. PIB obtained from PAA/PAME and PAME/PAME blends gave a similar thermal stability in TGA measurements and a superior mechanical property in comparison with PIB obtained from PAA/PAA blend.

Keywords:poly(amic methylester)(PAME);polyimide blend(PIB);thermal and mechanical properties
