| description | Provided are: production of a polycarbonate resin which has excellent characteristics such as transparency heat resistance mechanical strength and impact resistance while having a good color tone; and a polycarbonate resin composition which contains the polycarbonate resin. A method for producing a polycarbonate resin wherein a carbonic acid diester and a dihydroxy compound are subjected to a polycondensation reaction in the presence of a transesterification catalyst. This method for producing a polycarbonate resin is characterized in that the transesterification catalyst contains a phosphorus compound represented by general formula (1) and/or (2) and at least one basic compound that is selected from the group consisting of compounds of the group 1 elements of the long form periodic table (excluding hydrogen) compounds of the group 2 elements of the long form periodic table basic boron compounds basic phosphorus compounds and nitrogen containing basic compounds. |
