Novel copolymers, graft copolymers, copolymer particles, flame retardants, and resin compositions are provided. It has at least a unit derived from the monomer (B) having a polymer (A) portion having a glass transition temperature of −10 ° C. or lower, two or more aromatic rings and one or more radical reactive groups in one molecule. A copolymer comprising a polymer (C) moiety, a graft copolymer grafted with the component (B), and copolymer particles, using these copolymers as flame retardants, and using the flame retardant as a resin It is set as the resin composition which mix | blended and made flame-retardant.
