Method for producing polycarbonate resin, polycarbonate resin pellets and stretched film |
| abstract |
The present invention pertains to a method for producing a polycarbonate resin by continuously feeding a carbonic acid diester and a dihydroxy compound containing a dihydroxy compound having a fluorene structure, with a polymerization catalyst, to reaction vessels, and conducting polycondensation. This method for producing a polycarbonate resin is characterized in that: the reaction vessels consists of at least a plurality of vessels connected in a series; the temperature inside the reaction vessel one before the last polymerization reaction vessel is 200°C to 225°C; and the melt viscosity of the reaction solution at the outlet of the reaction vessel one before the last polymerization reaction vessel is 20 Pa⋅s to 1000 Pa⋅s. |
