The present invention relates to a process for producing a graft copolymer latex by emulsion-polymerizing a conjugated diene polymer, an aromatic vinyl monomer and an alkyl (meth) acrylate monomer, And a step of introducing an imidazole-based ionic compound into the graft copolymer latex and coagulating the graft copolymer. The present invention also relates to a copolymer composition and a thermoplastic resin composition containing the graft copolymer composite. |
