Abstract:
1. A process for producing a thermoplastic resin by reacting a dihydroxy component containing 30 mole % or more of 9,9-bis(4-(2-hydroxyethoxyl)phenyl)fluorene with at least one component selected from the group consisting of a dicarboxylic acid component and a carbonic acid ester component, wherein the 9,9-bis(4-(2-hydroxyethoxyl)phenyl)fluorine is produced by reacting phenoxyethanol and fluoren-9-one, wherein the thermoplastic resin is selected from the group consisting of polycarbonate resin, polyester resin, and polyester carbonate resin, wherein the purity of 9,9-bis(4-(2-hydroxyethoxyl)phenyl)fluorene is 99 wt % or more, and the content of phenoxyethanol is 1 to 500 ppm, wherein thermoplastic resin has a content of phenyl vinyl ether represented by the following formula (1) of 100 ppm or less, and and wherein thermoplastic resin has a content of acetaldehyde represented by the following formula (2) of 200 ppm or less,
