| titleOfInvention | Process for the preparation of aromatic polycarbonate |
| abstract | In the method of producing an aromatic polycarbonate by transesterifying an aromatic diester and an aromatic dihydroxy compound, the aromatic diester is obtained by the decarbonylation reaction of the aromatic oxalic acid diester of the formula A method for producing an aromatic polycarbonate, wherein the amount of hydrolyzable halogen contained therein is 5 ppm or less.n n n Formula 1n n n n n n n n In the above formula,n n n Ar is the same or different aromatic hydrocarbon group having 6 to 14 carbon atoms.n n n According to the present invention, when an aromatic polycarbonate is produced by using an aromatic carbonate diester obtained by decarbonylation of an aromatic oxalic acid diester and the amount of hydrolyzable halogen contained in the aromatic carbonate diester below a specific value, A high molecular weight aromatic polycarbonate can be produced easily and with excellent color without compromising exchange reactivity. |
