    摘要： The purpose of the present invention is to provide a polyester resin or polyester carbonate resin, which has high refractive index, while achieving an excellent balance between heat resistance and low birefringence. A polyester resin or a polyester carbonate resin, which contains repeating units represented by the following formulae (1) and (2), and wherein the ratio of the repeating unit represented by formula (1) to the repeating unit represented by formula (2) is 15:85 to 85:15. (In formula (1), each of rings Z1 and Z2 represents a polycyclic aromatic hydrocarbon group having 9-20 carbon atoms; each of R1, R2, R7 and R8 independently represents a hydrocarbon group which may contain an aromatic group having 1-12 carbon atoms; each of R3-R6 and R9-R16 represents a hydrogen atom or an aliphatic or aromatic substituents; each of j, k, r and s independently represent an integer of 0 or more; and each of m, n, p and q independently represents 1 or 2) (In formula (2), each of R7, R8, R17 and R18 independently represent a hydrocarbon group which may contain an aromatic group having 1-12 carbon atoms; each of R9-R16 and R19-R26 represents a hydrogen atoms or an aliphatic or aromatic substituents; and each of r, s, t and u independently represents an integer of 0 or more.)

    摘要： 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.)
