| titleOfInvention | Method for the Preparation of High Polymerized Aromatic Polycarbonate using Horizontal Tubular Reactor and the Apparatus thereof |
| abstract | The present invention post-polymerizes a polycarbonate prepolymer produced by melt transesterification of a carbonate ester and a diol compound using a horizontal tubular reactor. The present invention relates to a method and apparatus for producing an aromatic polycarbonate having a high degree of polymerization by postpolymerization.n n n More specifically, the present invention uses a horizontal tubular reactor consisting of a rotating plate, several compartments partitioned by a rotating plate, and an exhaust port to postpolymerize the polycarbonate prepolymer, thereby continuously increasing the degree of polymerization of the polycarbonate as the reactant moves through the compartment. By adjusting the feed rate of the polycarbonate prepolymer, thereby controlling the residence time of the reactants to obtain a polycarbonate having a desired degree of polymerization, and discharging the by-product aromatic alcohol through the doubling. It is to prevent. |
