Abstract

Abstract A composition of terminal-modified imide oligomers is disclosed. The composition comprises a flexible terminal-­modified imide oligomer (A) and a rigid terminal-modified imide oligomer (B). The flexible terminal-modified imide oligomer (A) is selected from specific oligomers (I) and (II). The rigid terminal-modified imide oligomer (B) is selected from specific oligomers (III) and (IV). The oligomer (I) is formed from biphenyltetracarboxylic acid or its derivative, an aromatic diamine compound (a) and an un­saturated monoamine compound or an unsaturated carboxylic acid or its derivative. The oligomer (II) is formed from biphenyltetracarboxylic acid or its derivative and an un­saturated monoamine compound. The oligomer (III) is formed from biphenyltetracarboxylic acid or its derivative, an aromatic diamine compound (b) and an unsaturated monoamine compound or an unsaturated carboxylic acid or its deriva­tive. The oligomer (IV) is formed from pyromellitic acid or its derivative, an aromatic diamine compound (c) and an unsaturated monoamine compound or an unsaturated carboxylic acid or its derivative. The aromatic diamine compound (a) has two or more aromatic rings which are combined with each other directly or by a divalent group consisting of one, two or three atoms. The aromatic diamine compound (b) has only one aromatic ring or condensed ring. The aromatic di­amine compound (c) may have two or more aromatic rings as is defined in the compound (a), or may have only one aro­matic ring or condensed ring as is defined in the compound (b).
