PURPOSE: A thermoplastic resin composition remarkably improved in blow moldability by using two kinds of butadiene-based graft copolymers having different molecular weights is provided, which can be used for the manufacture of blow molded products such as panel parts, car spoilers or plastic bottles. CONSTITUTION: The resin composition comprises 50 to 70 parts by weight of an alpha-methylstyrene copolymer obtained by copolymerization of 65 to 78 parts by weight of alpha-methylstyrene and 35 to 22 parts by weight of acrylonitrile; 30 to 50 parts by weight of a butadiene-based graft copolymer mixture and 15 to 0 parts by weight of a copolymer of an aromatic vinyl-based monomer and a cyanided vinyl-based monomer. |
