(식중, Ar은 탄소수 6∼27이고, 모노방향족기, 축합폴리방향족기 및 방향족기가 직결 또는 가교원을 통해 서로 연결된 비축합폴리방향족기로 이루어지는 군에서 선택된 4가기이며, 트리플루오르메틸기는 피리딘핵에 3- 혹은 4위치에 존재하며, 이미드질소원자는 에테르결합에 대해 3- 혹은 4위치에 연결되어 있다)로 표현된 1개 이상의 반복구조단위로 이루어진 폴리이미드이다.
본 발명의 폴리이미드 혹은 폴리이미드공중합체는 내열성이 우수하고, 용융유동안전성이 뛰어나며, 성형가공성이 향상되어 있고, 또, 무색투명으로 저유전율을 지녀 전기·전자기기, 광학기구를 위한 원료로서의 사용이 기대된다.
The present invention is a colorless and transparent and that having the dielectric properties containing a novel fluorinated polyimide or a polyimide copolymer and an aromatic diamino compound of the newly used in the polyimide, a method of manufacturing the same, a polyimide or a polyimide copolymer and a fibrous reinforcement consisting polling imide resins composition, method of producing the resin composition, the present invention relates to an injection molded article of the resin composition. That is, the present invention as an essential structural unit represented by the general formula (1) (Wherein, Ar is a 6-27 carbon atoms, and the mono-aromatic group, a condensed polycyclic aromatic group and an aromatic group selected from the group consisting of the top 4 total aromatic polyester reserve connected to each other via a direct connection or cross-linked source, trifluoro methyl group in the pyridine nucleus It is present in the 3-or 4-position, a polyimide-imide nitrogen who is connected to the ether linkage in the 3-or 4-position) consisting of at least one repeating structural unit represented by. A polyimide or a polyimide copolymer of the present invention is excellent in heat resistance and melt flow stability, and molding processability is improved, and, using as a raw material for electric and electronic devices, optical instruments jinyeo a low dielectric constant as a colorless transparent this is expected.
