| titleOfInvention | Method for producing aromatic polycarbonate resin |
| abstract | (57) [Summary] [Object] To provide a method for producing an aromatic polycarbonate resin which does not contain halogen, has excellent thermal stability, and does not pollute the environment. [Structure] A chloroformate group-containing aromatic polycarbonate oligomer is reacted with a monofunctional phenol compound to produce a phenylcarbonate group-containing aromatic polycarbonate oligomer, which is further polymerized by a transesterification method. In producing an aromatic polycarbonate resin, a chloroformate group-containing aromatic polycarbonate oligomer dissolved in a non-halogen solvent, and 1 to 10 equivalents of a monofunctional phenol compound alkali relative to 1 equivalent of the chloroformate group A phenyl carbonate group-containing aromatic polycarbonate oligomer soluble in a non-halogen organic solvent is produced by causing an interfacial reaction with a salt aqueous solution under the condition that the pH of the reaction solution is 12 or less, and the phenyl carbonate group-containing aromatic polycarbonate oligomer is melt-polymerized and / or solid phased. Does not contain halogen as a raw material for polymerization A method for producing an aromatic polycarbonate resin. |
