| titleOfInvention | Method for producing aromatic-aliphatic copolymerized polycarbonate |
| abstract | PROBLEM TO BE SOLVED: To produce an aromatic-aliphatic copolymer polycarbonate having excellent hue and heat stability, which is useful as an optical material or the like. SOLUTION: An aromatic-aliphatic copolymer obtained by melt-polymerizing an aromatic carbonic diester with at least one aliphatic dihydroxy compound having an alicyclic structure and at least one aromatic dihydroxy compound in the presence of a transesterification catalyst. In the method for producing a polycarbonate, an aromatic carbonate diester, an aromatic dihydroxy compound and an alkali metal or alkaline earth metal catalyst are mixed, and the mixture obtained by dissolving the aromatic dihydroxy compound in the aromatic carbonate diester by the progress of the transesterification reaction is mixed with a fat. A method for producing an aromatic-aliphatic copolymerized polycarbonate, which is polymerized with an aliphatic dihydroxy compound having a ring structure. |
