| titleOfInvention | Method for producing polycarbonate resin |
| abstract | The present invention relates to a method for producing a polycarbonate resin, and in particular, is polymerized under a catalyst of a mixture of a phosphoranilidene ammonium salt or a phosphoranilidene ammonium salt and a compound containing an alkali metal or an alkaline earth metal, and is stable under melt polymerization conditions. It has the effect of being able to efficiently produce a polycarbonate resin having a high molecular weight in a short time while maintaining excellent catalytic activity in the melt polymerization and solid phase polymerization processes. |
