Title (EN) POLYIMIDE PRECURSOR SOLUTION AND POLYIMIDE FILM PRODUCED USING SAME
(FR) SOLUTION DE PRÉCURSEUR DE POLYIMIDE ET FILM DE POLYIMIDE PRODUIT À L'AIDE DE CELLE-CI
(KO) 폴리이미드 전구체 용액 및 이를 이용하여 제조된 폴리이미드 필름
Abstract:
(EN) The present invention relates to the production of a polyimide precursor, whereby, by using an amide-based organic solvent having a positive-number partition coefficient (LogP) and a density of at most 1 g/cm3, an interaction between the organic solvent and polyamic acid, which is a polyimide precursor, may be mitigated, thereby enabling the decrease of the viscosity of a polyimide precursor solution, and thus enabling a polyimide precursor solution having high solid content and low viscosity to be obtained.
(FR) La présente invention concerne la production d'un précurseur de polyimide, dans le cadre de laquelle, en utilisant un solvant organique à base d'amide présentant un coefficient de partage positif (LogP) et une densité d'au plus 1 g/cm3, l'interaction entre le solvant organique et l'acide polyamique, qui est un précurseur de polyimide, peut être atténuée, ce qui permet de réduire la viscosité d'une solution de précurseur de polyimide et, ainsi, d'obtenir une solution de précurseur de polyimide présentant une teneur élevée en matières solides et une faible viscosité.
(KO) 본 발명은 폴리이미드 전구체의 제조에 있어서 분배계수(LogP)가 양수이면서 밀도가 1 g/cm3 이하인 아마이드계 유기용매를 사용함으로써 폴리이미드 전구체인 폴리아믹산과 유기용매간의 상호작용을 완화시켜 폴리이미드 전구체 용액의 점도를 저하시킬 수 있어 고 고형분 저 점도의 폴리이미드 전구체 용액을 얻을 수 있다.
