| titleOfInvention | Preparation of polycarbonate resin |
| abstract | BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a polycarbonate resin, and in particular, a quaternary phosphonium-based organic basic compound bonded to an amino group, or polymerized and melted under a mixed catalyst of an organic basic compound and a compound containing an alkali metal or an alkaline earth metal. The present invention relates to a method for producing a polycarbonate resin, which is stable under polymerization conditions, has excellent reactivity, and can efficiently prepare a high molecular weight polycarbonate resin by maintaining excellent catalytic activity in melt polymerization and solid phase polymerization processes. |
