A copolymerized polycarbonate resin of the present invention comprises: a repeating unit represented by the chemical formula 1; a repeating unit represented by the chemical formula 2; and a repeating unit represented by the chemical formula 3. The copolymerized polycarbonate resin has excellent chemical resistance, flame retardancy, low temperature impact resistance and the like. In the chemical formula 1, 2, and 3, R_1, R_2, R_3, R_4, R_5 and R_6 each independently represent a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, and a, b, c, d, e, and f are each independently an integer of 0 to 4. |
