| titleOfInvention | Method for producing optical polyester resin |
| abstract | The present invention relates to an optical polyester resin excellent in heat resistance and wavelength dispersibility suitable for an optical substrate such as a retardation film, and excellent in production stability and quality stability by suppressing excessive distillate during polycondensation. A manufacturing method is provided. A component having a fluorene skeleton and having a monomer unit molecular weight of 82 or more in the feed composition is 80 mol% or more, and a distillate weight X excluding a substantial excess component for transesterification during polymerization is included in the feed amount. On the other hand, a method for producing optical polyester that satisfies certain conditions. [Selection figure] None |
