Process for the manufacture of polycarbonate compositions |
| abstract |
A method for continuous production of polycarbonate, the continuous production method comprising: combining an aromatic dihydroxy compound stream and a diaryl carbonate stream to form a mixture; Controlling a weight ratio or a molar ratio of the diaryl carbonate to the aromatic dihydroxy compound, wherein the weight ratio or the molar ratio is controlled by measuring a sound velocity (Vs) in the mixture at an operating temperature of the control step; And determining a weight ratio or molar ratio of the diaryl carbonate to the aromatic dihydroxy compound in the mixture; And adjusting the flow rate of at least one of the aromatic dihydroxy compound stream and the diaryl carbonate stream to reach a desired weight ratio or molar ratio of the diaryl carbonate to the aromatic dihydroxy compound, if necessary; And polymerizing the aromatic dihydroxy compound and the diaryl carbonate in the presence of a catalyst to prepare the polycarbonate. |
