| abstract | (57) [Summary] [Purpose] Coloring is extremely small due to transesterification, Provided is a method for producing a polycarbonate having good hydrolysis stability. [Structure] In a method for producing a polycarbonate by reacting a carbonic acid diester with a dihydroxydiaryl compound, a contact portion of a reactor with a reaction solution is a corrosion-resistant or wear-resistant alloy made of a specific cobalt-based alloy or a specific nickel-based alloy. Using the polymerization device formed, the ratio of the carbonic acid diester and the dihydroxydiaryl compound in molar ratio A method for producing a polycarbonate having excellent thermal stability and a good color tone, which is characterized in that the range is 1.05 to 1.15. |
