| titleOfInvention | Polyester resin or polyester carbonate resin, and optical member using said resin |
| abstract | 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 Z 1 and Z 2 represents a polycyclic aromatic hydrocarbon group having 9-20 carbon atoms; each of R 1 , R 2 , R 7 and R 8 independently represents a hydrocarbon group which may contain an aromatic group having 1-12 carbon atoms; each of R 3 -R 6 and R 9 -R 16 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 R 7 , R 8 , R 17 and R 18 independently represent a hydrocarbon group which may contain an aromatic group having 1-12 carbon atoms; each of R 9 -R 16 and R 19 -R 26 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.) |
