<p>A graft copolymer (G) obtained by grafting at least one monomer selected among aromatic alkenyl compounds, methacrylic esters, acrylic esters, and vinyl cyanide compounds onto a rubbery polymer comprising 0 to 50 wt.% butadiene units and 50 to 100 wt.% alkyl (meth)acrylate units through emulsion polymerization, characterized by containing an emulsifier residue in an amount of 0.5 to 2.0 wt.%. A thermoplastic resin composition containing the graft copolymer is reduced in gas generation during molding, gives a molding having a satisfactory gloss, and is excellent in weatherability, impact resistance, and flowability.</p> |
