| titleOfInvention | The method for continuous production of high molecular weight polycarbonate resin |
| abstract | The present invention provides the method for continuous production of the high molecular weight polycarbonate resin of a kind of improvement, in the method, make aromatic copolycarbonate prepolymer and binary aliphatic alcoholic compound be attached macromolecule and quantify reaction, manufacture high molecular weight polycarbonate resin continuously, even the binary aliphatic alcoholic compound that boiling point is relatively low, it also is able to make it be actively engaged in connecting macromolecule and quantifies reaction, it is possible to advantageously manufacture the high molecular weight polycarbonate resin of excellent quality at economic aspect.Make aromatic dihydroxy compound and carbonic diester generation polycondensation reaction, manufacture aromatic copolycarbonate prepolymer, add the binary aliphatic alcoholic compound with the aliphatic group being combined with terminal hydroxyl wherein, obtain pre-polymer mixture, make this pre-polymer mix occur to connect macromolecule at reduced pressure conditions and quantify reaction, in the method, after adding binary aliphatic alcoholic compound with the pressure more than 200torr, before the terminal hydroxyl concentration of the aromatic copolycarbonate prepolymer in pre-polymer mixture reaches 2000ppm, supplying to connection macromolecule quantization reaction should pre-polymer mixture. |
