  Provided are: a transparent polyimide copolymer which satisfies solvent solubility, storage stability, heat resistance, mechanical strength and thermal yellowing resistance at high levels and has excellent utility; a polyimide resin composition; a molded article; and a production method of the copolymer. The transparent polyimide copolymer is obtained by copolymerizing: (A) 4,4′-oxydiphthalic dianhydride and/or 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane dianhydride; and (B) at least one diamine and/or diisocyanate represented by the following Formulae (1) to (3): (wherein, X represents an amino group or an isocyanate group; R1 to R8 each independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkenyl group having 2 to 4 carbon atoms or an alkoxy group having 1 to 4 carbon atoms; and at least one of the R1 to R8 is not a hydrogen atom).

  本发明提供了：一种透明聚酰亚胺共聚物，其溶剂溶解性、贮存稳定性、耐热性、机械强度和耐热黄变性均达到较高水平，且具有优异的实用性；一种聚酰亚胺树脂组合物；一种成型品；以及该共聚物的生产方法。透明聚酰亚胺共聚物是通过共聚以下物质而得到的：(A)4,4′-氧二邻苯二甲酸二酐和/或 2,2-双(3,4-二羧基苯基)六氟丙烷二酐；和(B)至少一种由下式(1)至(3)代表的二胺和/或二异氰酸酯： (其中，X 代表氨基或异氰酸酯基团；R1 至 R8 各自独立地代表氢原子、具有 1 至 4 个碳原子的烷基、具有 2 至 4 个碳原子的烯基或具有 1 至 4 个碳原子的烷氧基；且 R1 至 R8 中至少有一个不是氢原子）。
