Title (EN) POLYIMIDE HAVING FLUORENE SKELETON
(FR) POLYIMIDE COMPORTANT UN SQUELETTE FLUORÈNE
(JA) フルオレン骨格を有するポリイミド
Abstract:
(EN) The present invention addresses the problem of providing a novel polyimide which has a fluorene skeleton and which has low birefringence, and it was found that this problem can be solved by a polyimide which has a constituent unit derived from an amine represented by general formula (1) and a constituent unit derived from an acid dianhydride in the main chain. Provided is a polyimide which has a constituent unit derived from an amine represented by general formula (1) and a constituent unit derived from an acid dianhydride in the main chain. (In general formula (1): R1 and R2 each independently denote an alkyl group having 1-12 carbon atoms, a halogen atom, a hydroxyl group, a cycloalkyl group optionally having a substituent group having 4-12 carbon atoms, or an aromatic group optionally having a substituent group having 6-12 carbon atoms; and m and n are each an integer between 0 and 4. Moreover, in cases where a plurality of R1 and/or R2 groups are present, these may be the same as, or different from, each other.)
(FR) La présente invention concerne un nouveau polyimide qui comporte un squelette fluorène et présente une faible biréfringence. Le polyimide selon l'invention comporte un motif constitutif dérivé d'une amine représentée par la formule générale (1), et un motif constitutif dérivé d'un dianhydride d'acide dans la chaîne principale. L'invention se réfère à un polyimide qui comporte un motif constitutif dérivé d'une amine représentée par la formule générale (1), et un motif constitutif dérivé d'un dianhydride d'acide dans la chaîne principale. (Dans la formule générale (1) : R1 et R2 représentent chacun indépendamment un groupe alkyle doté de 1 à 12 atomes de carbone, un atome d'halogène, un groupe hydroxyle, un groupe cycloalkyle comportant éventuellement un groupe substituant doté de 4-12 atomes de carbone, ou un groupe aromatique comportant éventuellement un groupe substituant doté de 6-12 atomes de carbone ; et m et n représentent chacun un nombre entier compris entre 0 et 4. De plus, dans les cas où une pluralité de groupes R1 et/ou R2 sont présents, ceux-ci peuvent être identiques ou différents).
(JA) 本発明の課題は、フルオレン骨格を有するポリイミドであって、低複屈折性を有する新規なポリイミドを提供することであり、下記一般式(1) で表されるアミン類由来の構成単位、及び酸二無水物由来の構成単位を主鎖に含むポリイミドとすることにより、前記課題が解決可能であることを見出した。 下記一般式(1)で表されるアミン類由来の構成単位、及び酸二無水物由来の構成単位を主鎖に含むポリイミド。 (上記一般式(1)中、R及びRはそれぞれ独立して炭素数1~12のアルキル基、ハロゲン原子、ヒドロキシル基、炭素数4~12の置換基を有してもよいシクロアルキル基、又は炭素数6~12の置換基を有してもよい芳香族基を表し、m及びnは0~4の整数を表す。なお、R及び/又はRが複数存在する場合、それぞれは同一でも異なっていてもよい。)
