摘要： A branched aromatic polycarbonate resin having a degree of branching (N value) controlled within a specific range is manufactured by subjecting an aromatic polycarbonate prepolymer that has a branched structure introduced using a specific amount of a branching agent to molecular-weight-increasing linking reaction with an aliphatic diol compound in the presence of a transesterification catalyst under the condition of a reduced pressure. The amount (A) of the branching agent used is adjusted on the basis of the correlation between the amount (A) of the branching agent used and the N value of the branched aromatic polycarbonate resin.

摘要： [Problem] To provide a process for manufacturing, easily and using a conventional branching agent, a branched aromatic polycarbonate resin which has both a sufficiently high molecular weight and a desired degree of branching. [Solution] A branched aromatic polycarbonate resin having a degree of branching (N value) controlled within a specific range is manufactured by subjecting an aromatic polycarbonate prepolymer that has a branched structure introduced using a specific amount of a branching agent to molecular-weight-increasing linking reaction with an aliphatic diol compound in the presence of a transesterification catalyst under the condition of a reduced pressure. The amount (A) of the branching agent used in adjusted on the basis of the correlation between the amount (A) of the branching agent used and the N value of the branched aromatic polycarbonate resin.
