A thermoplastic resin composition includes 18 to 44 parts by mass of a copolymer (A) and 56 to 82 parts by mass of a copolymer (B) so that the total is 100 parts by mass, and further includes 0.1 to 0.3 parts by mass of an alkaline earth metal oxide (M) with respect to 100 parts by mass of the total of the graft copolymer (A) and the copolymer (B). Graft copolymer (A) is obtained by graft copolymerization a monomer mixture (II) containing an aromatic vinyl based monomer and a vinyl cyanide based monomer in the presence of a composite rubber polymer (I). The polymer (I) is composed of a diene rubber (i) and a cross-linked acrylic acid ester polymer (ii). Copolymer (B) is obtained by polymerization of a monomer mixture containing an aromatic vinyl based monomer and a vinyl cyanide based monomer.

Thermoplastic resin composition and resin molded article

A thermoplastic resin composition that includes 100 parts by mass of a first vinyl (co)polymer (I) that is produced by (co)polymerization of at least one monomer component selected from the group consisting of aromatic vinyl compounds, vinyl cyanide compounds, and other vinyl monomers copolymerizable with these compounds, and 1 to 100 parts by mass of a vinyl copolymer (II) that is produced by copolymerization of a vinyl cyanide compound and another vinyl monomer copolymerizable with the vinyl cyanide compound and in which the content of the vinyl cyanide compound component in an acetone soluble fraction of the copolymer ranges from 0.1% to 15% by mass.
