  An aromatic polysulfone produced by polymerizing a dihalogeno compound represented by general formula (A) shown below, and a dihydric phenol represented by general formula (B) shown below, the aromatic polysulfone having a value (Mw/Mn) for the ratio between the weight average molecular weight (Mw) and the number average molecular weight (Mn) of less than 1.8, and having a number average molecular weight (Mn) of at least 6,000 but less than 14,000. (In the formula, each of X and X′ independently represents a halogen atom; each of R1, R2, R3 and R4 independently represents an alkyl group having a carbon number of 1 to 4 or an alkoxy group having a carbon number of 1 to 4; each of n1, n2, n3 and n4 independently represents an integer of 0 to 4; and when n1, n2, n3 or n4 is an integer of 2 to 4, the plurality of R1, R2, R3 or R4 groups may be the same as, or different from, each other).

  一种芳香族聚砜，由下图所示通式(A)代表的二卤化合物和下图所示通式(B)代表的二水苯酚聚合而成，该芳香族聚砜的重量平均分子量(Mw)和数量平均分子量(Mn)的比值(Mw/Mn)小于1.8，且数量平均分子量(Mn)至少为6,000，但小于14,000。 (在式中，X 和 X′各自独立地代表卤素原子；R1、R2、R3 和 R4 各自独立地代表碳数为 1 至 4 的烷基或碳数为 1 至 4 的烷氧基；n1、n2、n3 和 n4 各自独立地代表 0 至 4 的整数；当 n1、n2、n3 或 n4 为 2 至 4 的整数时，多个 R1、R2、R3 或 R4 基团可彼此相同或不同）。
