    摘要： 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°C or more, for example, a temperature of 230 to 300°C, or 230 to 250°C.
