POLYIMIDE RESIN COMPOSITION AND VARNISH PRODUCED FROM TERMINAL-MODIFIED IMIDE OLIGOMER PREPARED USING 2-PHENYL-4,4'-DIAMINODIPHENYL ETHER AND THERMOPLASTIC AROMATIC POLYIMIDE PREPARED USING OXYDIPHTHALIC ACID, POLYIMIDE RESIN COMPOSITION MOLDED ARTICLE AND PREPREG HAVING EXCELLENT HEAT RESISTANCE AND MECHANICAL CHARACTERISTIC, AND FIBER-REINFORCED COMPOSITE MATERIAL THEREOF

摘要

An imide resin composition including a terminal-modified imide oligomer of General Formula (1) and a thermoplastic aromatic polyimide of General Formula (2). (In Formula (1), either R₁ or R₂ shows a phenyl group and the other shows a hydrogen atom; R₃ and R₄ show a divalent residue of aromatic diamine; R₅ and R₆ show a tetravalent residue of aromatic tetracarboxylic acid; m and n satisfy relationships of m≧1, n≧0, 1≦m+n≦20, and 0.05≦m/(m+n)≦1; and an arrangement of repeating units may be either a block or random.) (In Formula (2), R₁ and R₂ show a divalent residue of aromatic diamine; R₃ shows a tetravalent residue of aromatic tetracarboxylic acid; m and n satisfy relationships of m≧1 and n≧0, and an arrangement of repeating units may be either a block or random.)
