摘要： Provided is a graft copolymer that has an excellent impact-resistance-imparting effect and that can provide a thermoplastic resin composition excellent in weather resistance and color developability. A graft copolymer (C) obtained by graft-polymerizing one or two or more monomers (B), which are selected from (meth)acrylic acid esters, aromatic vinyls, vinyl cyanides, N-substituted maleimides, and maleic acid, onto a composite rubber-like polymer (A), which is obtained by polymerizing a mixture (Ac) containing a polyorganosiloxane (Aa) and an acrylic acid ester (Ab) after forming a miniemulsion in water solvent. A thermoplastic resin composition that contains the graft copolymer (C) and a thermoplastic resin (D).
