Title (EN) POLYIMIDE, POLYIMIDE VARNISH, AND POLYIMIDE FILM
(FR) POLYIMIDE, VERNIS DE POLYIMIDE ET FILM DE POLYIMIDE
(JA) ポリイミド、ポリイミドワニス、及びポリイミドフィルム
Abstract:
(EN) The present invention provides: a polyimide having a structural unit A that includes a structural unit (A-1) derived from a compound represented by formula (a-1) and a structural unit (A-2) derived from a compound represented by formula (a-2), and a structural unit B that includes a structural unit (B-1) derived from a compound represented by formula (b-1) and a structural unit (B-2) derived from a compound represented by formula (b-2); and a polyimide varnish and a polyimide film that include said polyimide. The polyimide can form a film that has a low linear thermal expansion coefficient while maintaining high transparency and high heat resistance, and the polyimide varnish and polyimide film include said polyimide. (In formula (b-1), R's each independently represent a hydrogen atom, a fluorine atom, or a methyl group.)
(FR) La présente invention concerne : un polyimide ayant une unité structurale A qui comprend une unité structurale (A-1) dérivée d'un composé représenté par la formule (a-1) et une unité structurale (A-2) dérivée d'un composé représenté par la formule (a-2), et une unité structurale B qui comprend une unité structurale (B-1) dérivée d'un composé représenté par la formule (b-1) et une unité structurelle (B-2) dérivée d'un composé représenté par la formule (b-2) ; et un vernis de polyimide et un film de polyimide qui comprennent ledit polyimide. Le polyimide peut former un film qui a un faible coefficient de dilatation thermique linéaire tout en conservant une transparence élevée et une résistance à la chaleur élevée, et le vernis de polyimide et le film de polyimide comprennent ledit polyimide. (Dans la formule (b-1), chaque R représente indépendamment un atome d'hydrogène, un atome de fluor ou un groupe méthyle.)
(JA) 本発明は、式(a-1)で表される化合物に由来する構成単位(A-1)、及び式(a-2)で表される化合物に由来する構成単位(A-2)を含む構成単位Aと、式(b-1)で表される化合物に由来する構成単位(B-1)、及び式(b-2)で表される化合物に由来する構成単位(B-2)を含む構成単位Bとを有するポリイミド、並びに該ポリイミドを含むポリイミドワニス及びポリイミドフィルムであり、高透明性及び高耐熱性を維持しつつ、低線熱膨張係数を有するフィルムを形成できるポリイミド、並びに該ポリイミドを含むポリイミドワニス及びポリイミドフィルムを提供する。 (式(b-1)中、Rはそれぞれ独立して、水素原子、フッ素原子又はメチル基を表わす。)
