| titleOfInvention | IMPROVED METHOD FOR MAKING AROMATIC POLYCARBONATE |
| abstract | A practical process in which a high quality, high performance aromatic polycarbonate with excellent mechanical properties and lack of any coloration can be produced stably on an industrial scale at a production rate ranging from 1 to 50 t / h for a long period of time from a molten aromatic polycarbonate prepolymer derived from an aromatic dihydroxy compound and a diaryl carbonate. In particular, there is provided a method for the production of an aromatic polycarbonate on an industrial scale in accordance with a melt process, comprising polymerizing a molten aromatic polycarbonate prepolymer obtained by reacting an aromatic dihydroxy compound and a diaryl carbonate using a downflow polymerizer in contact with a rail characterized by a specific structure, so that with a throughput in the range of 1 to 50 t / h for a long period of ≥ several 1000, for example ≥ 5000 h, high quality aromatic polycarbonate with high performance and excellent mechanical properties can be produced stably. properties and characterized by the absence of any color, without any fluctuation in molecular weight, and the like. |
