| abstract | (57) [Summary] [Purpose] To provide a method for producing a polycarbonate which has a small amount of residual catalyst and is excellent in quality such as hydrolysis resistance and has a high reaction rate and excellent productivity. . [Structure] When a polycarbonate is produced by transesterification of a dihydroxy compound as a monomer raw material and a carbonic acid diester by using an active hydrogen-containing nitrogen-containing heterocyclic compound and a metal compound as a catalyst, the dihydroxy compound or the carbonic acid diester is prepared in advance. A process for producing a polycarbonate, which comprises mixing the active hydrogen-containing nitrogen-containing heterocyclic compound and / or the metal compound and bringing them into contact with each other. |
