| abstract |
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, R<sup>1</sup>and R<sup>2</sup>independently represent a C1-C12 hydrocarbon group optionally including a hydrogen atom, a halogen atom, and an aromatic group, Ar<sup>1</sup>and Ar<sup>2</sup>represent a C6-C10 aromatic group optionally having a substituent, L<sup>1</sup>and L<sup>2</sup>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.) |
