| titleOfInvention | Polyester carbonate copolymer for optical lens and optical lens |
| abstract | An object of the present invention is to provide a polyester carbonate copolymer suitable for an optical lens having high refractive index and transparency, low birefringence and low optical distortion, and an optical lens using the same. The present invention contains 67 to 95 mol% of a unit represented by the following formula (I) and 33 to 5 mol% of a unit represented by the following formula (II), and has a specific viscosity of 0.12 to 0.005. 30 is a polyester carbonate copolymer for optical lenses. (In formula (II), Y represents a phenylene group or a naphthalenediyl group.) |
