| titleOfInvention | METHOD FOR CONTINUOUS PRODUCTION OF HIGH-MOLECULAR POLYCARBONATE RESIN |
| abstract | 1. A method for the continuous production of high molecular weight polycarbonate resin, which includes: process (A) production of an aromatic polycarbonate prepolymer by polycondensation of an aromatic dihydroxy compound with a diester carbonate in a polycondensation reactor and process (B) carrying out a crosslinking reaction and high polymerization of said aromatic polycarbonate prepolymer, (A), with an aliphatic diol compound in the crosslinking and high polymerization reactor, where indicated an aromatic polycarbonate prepolymer produced by said process (A), was continuously fed into a high crosslinking and polymerisation reactor, whereas said aliphatic diol compound is continuously fed into the reactor and high crosslinking polymerization under a reduced pressure of 10 Torr (1,333 Pa) or menshe.2. A method for the continuous production of a high molecular weight polycarbonate resin according to claim 1, wherein the residence time of the reaction mixture in said crosslinking and high polymerization reactor is 60 minutes or less. A method for the continuous production of a high molecular weight polycarbonate resin according to claim 1, wherein said aliphatic diol compound is a compound represented by the following general formula (A): wherein Q is a hydrocarbon group having at least 3 carbon atoms which may contain atoms of another species; R, RR and R each independently represents a group selected from the group consisting of a hydrogen atom, an aliphatic hydrocarbon group having 1-30 carbon atoms, and an aromatic hydrocarbon group having 6-20 carbon atoms, provided that, by m |
