摘要:
There is provided an elastomer composition for an impact modifier and a thermoplastic resin composition having improved impact resistance using the same. An elastomer composition comprises a block copolymer (a) containing a methacrylate polymer and a siloxane polymer, and a graft copolymer (b) containing a polymer component having a glass transition temperature of lower than 25° C. And the composition is mixed with a thermoplastic resin (c).
