| titleOfInvention | Method for producing polycarbonate resin |
| abstract | The present invention provides a method for producing a polycarbonate copolymer having excellent heat resistance, rigidity and improved hue. 5 to 95 mol% of a wholly aromatic dihydroxy component is represented by the following general formula [1], [Chemical 1] [Wherein, R 1 to R 4 each independently represent a hydrogen atom, a hydrocarbon group which may contain an aromatic group having 1 to 9 carbon atoms, or a halogen atom. The fluorene-based bisphenol represented by the formula: 95-5 mol% is represented by the following general formula [2] [Chemical 2] [Wherein, R 5 to R 8 are each independently a hydrogen atom, a hydrocarbon group or a halogen atom which may contain an aromatic group having 1 to 9 carbon atoms, and W is a single bond, having 1 to 1 carbon atoms. A hydrocarbon group optionally containing 20 aromatic groups, an O, S, SO, SO 2 , CO or COO group. ] A process for producing a polycarbonate resin comprising a dihydroxy component represented by formula (1), wherein the phosgenation reaction and the polymerization reaction are carried out substantially in the absence of oxygen.
