ABSTRACT:
A novel copolymer, graft copolymer, copolymer particles, flame retardant, and resin composition are provided. A copolymer including a polymer (A) segment having a glass transition temperature not more than −10° C., and a polymer (C) segment having at least a unit derived from a monomer (B) which has two or more of aromatic rings and one or more radical reactive groups in one molecule; a graft copolymer having the component (B) grafted onto the component (A); and copolymer particles thereof are obtained. A flame retardant resin composition is obtained by using the copolymer as a flame retardant and blending the flame retardant with the resin.
