Method for continuous production of high-molecular-weight-polycarbonate resin |
| abstract |
THE PRESENT INVENTION PROVIDES AN IMPROVED METHOD FOR CONTINUOUSLY PRODUCING A HIGH-MOLECULAR-WEIGHT POLYCARBONATE RESIN BY CARRYING OUT A LINKING AND HIGHLY-POLYMERIZING REACTION OF AN AROMATIC POLYCARBONATE PREPOLYMER WITH AN ALIPHATIC DIOL COMPOUND WHEREIN THE RETENTION TIME OF THE REACTION MIXTURE IN THE LINKING AND HIGHLY-POLYMERIZING REACTOR IS SHORTENED TO ACHIEVE EXCELLENT PERFORMANCE. THE PROCESS COMPRISES A PROCESS (A) FOR PRODUCING AN AROMATIC POLYCARBONATE PREPOLYMER BY POLYCONDENSATION REACTION OF AN AROMATIC DIHYDROXY COMPOUND WITH DIESTER CARBONATE AND A PROCESS (B) FOR CONDUCTING LINKING AND HIGHLY-POLYMERIZING REACTION OF THE AROMATIC POLYCARBONATE PREPOLYMER WITH AN ALIPHATIC DIOL COMPOUND IN THE LINKING AND HIGHLY-POLYMERIZING REACTOR, WHEREIN THE AROMATIC POLYCARBONATE PREPOLYMER PRODUCED THE PROCESS (A) IS FED CONTINUOUSLY TO THE LINKING AND HIGHLY-POLYMERIZING REACTOR, WHILE THE ALIPHATIC DIOL COMPOUND IS FED CONTINUOUSLY THERETO UNDER REDUCED PRESSURE OF 10 TORR OR LESS TO CARRY OUT THE REACTION.
