Abstract
(EN)
Provided is a method for producing a polyimide resin capable of forming a film which has a high flex resistance. A method for producing a polyimide resin, which comprises: process (I) for preparing an intermediate (K), said process including step (A) for reacting a diamine compound with a carboxylic acid compound having 3 or more carbonyl groups; and process (II) for further reacting the intermediate (K) with a diamine compound.
(FR)
L'invention concerne un procédé de production d'une résine polyimide capable de former un film qui a une résistance élevée à la flexion. L'invention concerne également un procédé de production d'une résine polyimide, qui comprend : un processus (I) pour préparer un intermédiaire (K), ledit procédé comprenant l'étape (A) pour faire réagir un composé diamine avec un composé d'acide carboxylique ayant 3 groupes carbonyle ou plus; et un procédé (II) pour faire réagir davantage l'intermédiaire (K) avec un composé diamine.
(JA)
耐屈曲性に優れたフィルムを形成可能なポリイミド系樹脂の製造方法を提供する。 ジアミン化合物と3つ以上のカルボニル基を有するカルボン酸化合物とを反応させるステップ(A)を含む中間体(K)を得る工程(I)、及び該中間体(K)に、さらにジアミン化合物を反応させる工程(II)を含む、ポリイミド系樹脂の製造方法。
