폴리이미드의 제조와 성질에 관한 연구 - IV. 6FDA계 폴리이미드
Studies on Synthesis and Properties of Polyimides : IV. 6FDA-Polyimides
초록
2,2-Bis-(3,4-dicarboxyphenyl)hexafluoropropane dianhydride(6FDA), 2,2-bis-[4-(4-aminophenoxy)phenyl]hexafluoropropane 및 4,4-diaminodiphenyl ether 등을 이용하여 단독폴리아믹산, 공폴리아믹산 및 폴리아믹산의 블렌드를 만들고, 열이미드화로 각각의 폴리이미드를 제조하여 구조와 성질을 조사하였다. 그 결과로 열이미드화 동안에 폴리아믹산 간의 교환반응이 일어난다는 것을 알았다. 그리고 공중합이나 폴리아믹산의 블렌드 방법으로 폴리이미드의 분자복합체를 얻을 수 있었다.
Using 2,2-Bis-(3,4-dicarboxyphenyl)hexafluoropropane dianhydride, 2,2-bis-[4-(4-aminophenoxy)phenyl] hexafluoropropane and 4,4-diaminodiphenyl ether, the homopolyamic acids, copolyamic acids and blend of homopolyamic acids were prepared and converted to polyimide(PI)s by thermal imidization. In results, it has been found that a exchange reaction of polyamic acids can be occurred during thermal imidization. With measurement of mechanical properties, it was suggested that PI/PI molecular composite can be obtained by copolymerization or physical blending of homopolyamic acids.
