Claim 12:
13. A graft copolymer with a core-shell structure, the graft copolymer comprising:
a rubbery polymer core;
and a shell wrapping the core and comprising a unit derived from an aromatic vinyl-based monomer and a unit derived from a vinyl cyan-based monomer,
wherein the rubbery polymer core comprises
from 3 parts by weight to 5 parts by weight of the diene-based rubber latex of claim 1, wherein the diene-based rubber latex of claim 1 has an average diameter of 600 nm to 800 nm,
and from 95 parts by weight to 97 parts by weight of a diene-based rubber latex with an average diameter of 310 nm to 330 nm based on 100 parts by weight of the core.
