Abstract:
1. A thermoplastic resin composition comprising: a graft copolymer and a thermoplastic resin, the graft copolymer being obtained by polymerizing monomers in a presence of hollow rubber particles; the monomers accounting for 10 to 70 parts by weight of the graft polymer, and containing a vinyl monomer and another monomer; the vinyl monomer accounting for 60 to 100% by weight of the monomers and being selected from the group consisting of a (meth)acrylate ester compound, an aromatic vinyl compound and a vinyl cyanide compound, and the other monomer accounting for 0 to 40% by weight of the monomers and being copolymerizable therewith; the hollow rubber particles accounting for 30 to 90 parts by weight of the graft copolymer having a porosity of 3 to 90% in a form of a latex, and being obtained by polymerizing a polymerization component without using a crosslinking agent, the polymerization component comprising a butadiene.
