PURPOSE: A polycarbonate terpolymer is provided to maintain the properties of polycarbonate and to improve flowability and thermal stability in a melt state. CONSTITUTION: A polycarbonate terpolymer comprises a repeating unit indicated in chemical formula 1, a repeating unit indicated in chemical formula 2, and a repeating unit indicated in chemical formula 3. In chemical formula 1, each of R1 and R2 is selected from C1-20 alkyl group, C4-20 cycloalkyl group, and C6-20 aryl group; each of a and b is an integer from 0-4; X is a chemical bond or selected from an oxygen atom, sulfur atom, -SO2-, C1-20 aliphatic radical, or -CR3R4-. |
