| titleOfInvention | The method for continuous production of high molecular weight polycarbonate resin |
| abstract | Problem of the present invention is the method for continuous production of the high molecular weight polycarbonate resin providing a kind of improvement, comprising: make aromatic dihydroxy compound and carbonic diester carry out polycondensation, obtains the operation (A) of aromatic copolycarbonate prepolymer; Quantize to carry out in reactor to connect the operation (B) that polymer quantizes to react with the aromatic copolycarbonate prepolymer making to obtain and binary aliphatic alkylol cpd being connected polymer.In this method for continuous production, can shorten and connect the residence time that polymer quantizes reactor reaction mixture, improve the performance of the polycarbonate resin obtained, the aromatic copolycarbonate prepolymer of above-mentioned operation (A) is supplied to continuously and connects polymer quantification reactor, and, under the condition of below degree of decompression 10torr, supply binary aliphatic alkylol cpd continuously, make them react. |
