| titleOfInvention | Method of producing polycarbonate resin |
| abstract | FIELD: chemistry. ^ SUBSTANCE: method of producing polycarbonate resin involves a reesterification reaction between an aromatic dihydroxy compound and diphenyl carbonate and/or substituted diphenyl carbonate. The molar ratio of diphenyl carbonate and/or substituted diphenyl carbonate to the aromatic dihydroxy compound ranges from 1.01 to 1.30. The aromatic polycarbonate resin is continuously produced with viscosity-average molecular weight from 10000 to 20000 for a certain period of time. When the reaction stops, the reactor is washed with a molten mixture of an aromatic dihydroxy compound with diphenyl carbonate and/or substituted diphenyl carbonate. The reactor is then washed with an aromatic monohydroxy compound. ^ EFFECT: providing a method of producing a polycarbonate resin, having a less intense colour and containing a low amount of undesirable crystalline impurities and such undesirable impurities as gel. ^ 2 cl, 1 tbl, 1 dwg, 2 ex |
