Abstract
A core-shell copolymer includes a core including an emulsifying initiator-derived layer derived from an emulsifying initiator, and a core forming monomer-derived repeating unit, bound to the emulsifying initiator-derived layer; and a shell including a shell forming monomer-derived repeating unit, wherein the emulsifying initiator comprising a surfactant part, an initiator part, and a vinyl monomer-derived repeating unit, the surfactant part including an organic acid-based monomer-derived repeating unit, and the initiator part including a peroxide-based monomer-derived repeating unit, wherein the emulsifying initiator has a weight average molecular weight less than 250,000 g/mol.
