| titleOfInvention | Method for producing aromatic polycarbonate |
| abstract | (57) [Summary] (Modifications) [Problem] To provide a method for producing an aromatic polycarbonate using a catalyst having excellent activity, and having a performance of losing thermal stability due to catalyst residue and the like and little generation of a colored substance. . Kind Code: A1 A method for producing an aromatic polycarbonate oligomer in which a bisalkyl carbonate (A) of an aromatic dihydroxy compound is used as a raw material and self-condensed using a quaternary ammonium salt represented by the following formula as a catalyst. Embedded image (Wherein R 1 and R 2 are an alkyl group having 1 to 10 carbon atoms or a cycloalkyl group having 3 to 10 carbon atoms, which may be the same or different from each other. Z is a divalent aromatic Residue.) |
