Process for manufacturing branched aromatic polycarbonate resin with desired degree of branching

摘要

Process for manufacturing a branched aromatic polycarbonate resin having a desired degree of branching comprising a process in which an aromatic polycarbonate prepolymer having a branched structure introduced using a predetermined amount of a branching agent is subjected to binding reaction and high polymerization under reduced pressure with an aliphatic diol compound having aliphatic hydrocarbon groups that bind to terminal OH groups.
