Title (EN) POLYIMIDE-BASED BLOCK COPOLYMER AND POLYIMIDE-BASED FILM COMPRISING SAME
(FR) COPOLYMÈRE SÉQUENCÉ À BASE DE POLYIMIDE ET FILM À BASE DE POLYIMIDE LE COMPRENANT
(KO) 폴리이미드계 블록 공중합체 및 이를 포함하는 폴리이미드계 필름
Abstract:
(EN) The present invention relates to a polyimide-based block copolymer and a polyimide-based film comprising the same. The polyimide-based block copolymer according to the present invention makes it possible to provide a polyimide-based film exhibiting excellent mechanical properties while being colorless and transparent. The polyimide-based film can be appropriately used as a cover film of various flexible or foldable devices.
(FR) La présente invention concerne un copolymère séquencé à base de polyimide et un film à base de polyimide le comprenant. Le copolymère séquencé à base de polyimide selon la présente invention permet d'obtenir un film à base de polyimide doué d'excellentes propriétés mécaniques tout en restant incolore et transparent qui peut être utilisé de manière appropriée comme film de couverture de divers dispositifs souples ou pliables.
(KO) 본 발명은 폴리이미드계 블록 공중합체 및 이를 포함하는 폴리이미드계 필름에 관한 것이다. 본 발명에 따른 폴리이미드계 블록 공중합체는 무색 투명하면서도 우수한 기계적 물성을 나타내는 폴리이미드계 필름의 제공을 가능케 한다. 상기 폴리이미드계 필름은 다양한 플렉시블 (flexible) 또는 폴더블 (foldable) 기기의 커버 필름 등으로 적합하게 사용될 수 있다.
