    • A polyimide resin composition is disclosed herein which comprises 5 to 60% by weight of a polyimide [polyimide (1)] having a repeating unit represented by the chemical formula 1 and 40 to 95% by weight of a polyimide [polyimide (2)] having a repeating unit represented by the chemical formula 2. According to the present invention, there are provided a polymer alloy in which the advantages of the polyimide (1) and the polyimide (2) are utilized and the disadvantages of the polyimide (1) and the polyimide (2) are reduced; a polyimide resin composition from which crystalline molded articles can be obtained even by a usual molding cycle, for example, an injection molding cycle of about 30 to 60 seconds; and a polyimide resin composition from which molded articles having an excellent dimensional accuracy and flexural modulus can be obtained even by a usual molding cycle, for example, an injection molding cycle of about 30 to 60 seconds, for example, in the case that the molded articles are intended to be used at a high temperature of 230.degree. C. or more, for example, a temperature of 230 to 300.degree. C., or 230 to 250.degree. C.
    • 本文公开了一种聚酰亚胺树脂组合物,其包含5至60重量%的具有由化学式1表示的重复单元的聚酰亚胺[聚酰亚胺(1)]和40至95重量%的聚酰亚胺[聚酰亚胺(2)] 具有由化学式2表示的重复单元。根据本发明,提供了使用聚酰亚胺(1)和聚酰亚胺(2)的优点的聚合物合金,并且聚酰亚胺(1) 并且聚酰亚胺(2)被还原; 聚酰亚胺树脂组合物,甚至可以通过通常的成型周期获得结晶模制品,例如约30至60秒的注塑周期; 以及聚酰亚胺树脂组合物,即使在通常的成型周期(例如,注射成型周期为约30〜60秒)下,也可以获得具有优异的尺寸精度和挠曲模量的成型制品,例如在成型 制品应在230℃或更高的高温下使用,例如温度为230-300℃,或230-250℃。
