The purpose of the present invention is to provide a thermoplastic resin that has a high refractive index and enables low birefringence and balanced heat resistance and moldability. This thermosetting resin includes repeating units represented by formula (1). (In the formula, the rings Z are the same or different and represent an aromatic hydrocarbon ring, R1 and R2 independently represent a C1-C12 hydrocarbon group optionally including a hydrogen atom, a halogen atom, and an aromatic group, Ar1 and Ar2 represent a C6-C10 aromatic group optionally having a substituent, L1 and L2 independently represent a divalent linking group, j and k independently represent an integer of 0 or more, m and n independently represent 0 or 1, and W is at least one selected from the groups represented by formulae (2) and (3).) (In the formula, X represents a divalent linking group.)
本发明的目的是提供一种热塑性树脂,它具有高折射率,可实现低双折射,并兼顾耐热性和成型性。这种热固性树脂包括由式(1)表示的重复单元。(式中,环 Z 相同或不同,代表芳香烃环;R1 和 R2 独立地代表 C1-C12 烃基,可选地包括氢原子、卤素原子和芳香基;Ar1 和 Ar2 代表 C6-C10 芳香基,可选地具有取代基;L1 和 L2 独立地代表二价连接基;j 和 k 独立地代表 0 或以上的整数;m 和 n 独立地代表 0 或 1;W 至少选自式(2)和(3)所代表的基团中的一个)。(式中,X 代表二价连接基团)。
