Method for producing aromatic-aliphatic copolymerized polycarbonate |
| abstract |
(57) [Problem] To provide a method for producing a transesterification aromatic-aliphatic copolymerized polycarbonate having high transparency and good hue. A dihydroxy compound having an aromatic diester and at least one alicyclic structure, and at least one dihydroxy compound having an alicyclic structure are provided. Certain aromatic dihydroxy compounds are converted to alkali metals and / or Alternatively, when producing an aromatic-aliphatic copolymerized polycarbonate by melt-polymerizing in the presence of an alkaline earth metal catalyst, BPZ having a total content of organic impurities of 100 ppm or less and a total content of metal impurities of 1 ppm or less is used. Used for raw materials. |
