PROBLEM TO BE SOLVED: To provide a novel copolymer polycarbonate resin having excellent optical properties, heat resistance and impact resistance, and a method for producing the same. SOLUTION: An aromatic-aliphatic copolymer polycarbonate resin synthesized from a specific aromatic dihydroxy compound, a specific aliphatic dihydroxy compound and a carbonic acid diester, and a method for producing the same. Specifically, 2,2-bis (4- (Hydroxyphenyl) propane, 3,9-bis (2-hydroxy-1,1-dimethylethyl) -2,4,8,1 The raw materials are 0-tetraoxaspiro (5.5) undecane, tricyclo (5.2.1.0 2,6 ) decanedimethanol, diphenyl carbonate, and sodium hydrogen carbonate. |
