| titleOfInvention | Method for producing polycarbonate resin |
| abstract | Disclosed is a method for producing a polycarbonate resin from which a polymer having a high molecular weight and excellent mechanical strength can be obtained. When polymerizing a cyclic polycarbonate oligomer, a triarylphosphonium salt having a structure represented by the general formula 1 is used as a polymerization catalyst in an amount of 0.6 mol% or more with respect to the amount of carbonate bonds in the cyclic polycarbonate oligomer. A method for producing a polycarbonate resin, comprising using the polycarbonate resin. In General Formula 1, R 1 represents a hydrogen atom, an alkyl group, an alkoxy group, or a phenyl group, R 2 represents an alkyl group, and X represents a halogen atom. [Selection figure] None |
