description Disclosed are a method of producing a graft copolymer, comprising polymerizing a vinyl monomer (B) containing a polyfunctional vinyl monomer (b1) in the presence of a polyorganosiloxane rubber (A) comprising more than 20% by mass of a toluene-insoluble matter, wherein a mass percentage of the polyfunctional vinyl monomer (b1) is 11 to 19% by mass based on 100% by mass of a total amount of the polyorganosiloxane rubber (A) and the vinyl monomer (B); a graft copolymer obtained by the method; a resin composition being prepared by blending the graft copolymer with a resin and having high impact resistance and heat resistance and sufficient flame retardancy; and a molded article obtained by molding the resin composition.
