A polyarylate resin is represented by general formula (1) shown below. In general formula (1), R1, R2, R3, and R4 each represent, independently of one another, a hydrogen atom or a methyl group. r and s each represent an integer of at least 0 and no greater than 49. t and u each represent an integer of at least 1 and no greater than 50. r + s + t + u = 100. r + t = s + u. r and t may be the same as or different from each other. s and u may be the same as or different from each other. X represents a divalent group represented by chemical formula (2A), (2B), (2C), or (2D). Y represents a divalent group represented by chemical formula (4A), c (4B), or (4C). X and Y are different from each other.
一种聚芳酯树脂由下图所示的通式(1)表示。在通式(1)中,R1、R2、R3 和 R4 各自独立地代表一个氢原子或一个甲基。R 和 s 各自代表至少为 0 且不大于 49 的整数。X 代表二价基团,化学式为 (2A)、(2B)、(2C) 或 (2D)。Y 代表由化学式 (4A)、c (4B) 或 (4C) 表示的二价基团。X 和 Y 互不相同。
