| description | The present invention relates to a polymer resin film including a polyamide-imide block copolymer having a weight average molecular weight of 100,000 to 800,000 and a PDI of 3 or less, having a yellowness of 3 or less, and having a 30,000 times or higher number of cycles of fracture occurring during a MIT folding test, and to a cover window for a flexible display device. The polymer resin film is colorless and transparent, and has excellent mechanical properties and high elasticity.
본 발명은 10만 내지 80만의 중량평균분자량 및 3이하의 PDI를 갖는 폴리아미드-이미드 블록 공중합체를 포함하고, 3이하의 황색도를 가지며, MIT 폴딩 테스트시 파단이 발생하는 사이클 수가 3만회 이상인 고분자 수지 필름과 플렉서블 디스플레이 장치의 커버 윈도우에 관한 것이다. |
