Flame resistant polycarbate based resin composition and molded articles thereof

A flame resistant polycarbonate-based resin composition comprising:

• a polycarbonate resin including an aromatic polycarbonate-based first repeating unit;
• a copolycarbonate resin including the aromatic polycarbonate-based first repeating unit and one or more aromatic polycarbonate-based second repeating unit having siloxane bonds;
• and
• an organic metal salt-based flame retardant,
• wherein each first repeating unit independently includes a repeating unit represented by Chemical Formula 1 below;
• and
• the second repeating unit includes a repeating unit represented by Chemical Formula 3 below:
• wherein, in Chemical Formula 1,
• R1 to R4 are each independently hydrogen, a C1-10 alkyl, a C1-10 alkoxy, or a halogen, and
• Z is a C1-10 alkylene unsubstituted or substituted with a phenyl, a C3-15 cycloalkylene unsubstituted or substituted with a C1-10 alkyl, O, S, SO, SO2, or CO;
• wherein, in Chemical Formula 3,
• each X2 is independently a C1-10 alkylene,
• each Y1 is independently hydrogen, a C1-6 alkyl, a halogen, a hydroxy, a C1-6 alkoxy, or a C6-20 aryl,
• each R6 is independently hydrogen;
• a C1-15 alkyl unsubstituted or substituted with an oxiranyl, an oxiranyl-substituted C1-10 alkoxy, or a C6-20 aryl;
• a halogen;
• a C1-10 alkoxy;
• an allyl;
• a C1-10 haloalkyl;
• or a C6-20 aryl, and
• n2 is an integer of 10 to 200.
