wherein the one or more aromatic polycarbonate-based second repeating units having siloxane bonds comprise a repeating unit represented by Chemical Formula 2 and a repeating unit represented by Chemical Formula 3:

in Chemical Formula 2,
each of X 1 is independently C 1-10 alkylene,
each of R 5 is independently hydrogen; C 1-15 alkyl unsubstituted or substituted with oxiranyl, oxiranyl-substituted C 1-10 alkoxy, or C 6-20 aryl; halogen; C 1-10 alkoxy; allyl; C 1-10 haloalkyl; or C 6-20 aryl, and
n is an integer of 10 to 50,

in Chemical Formula 3,
each of X 2 is independently C 1-10 alkylene,
