Disclosed is a thermoplastic resin composition comprised of (A) 10-60 weight parts of a polyphenylene ether resin, (B) 20-70 weight parts of (b-1) an aromatic vinyl resin and/or (b-2) a copolymer of an aromatic vinyl monomer with a heterocyclic compound having a vinyl group and containing nitrogen as the hetero atom and (C) 10-60 weight parts of (c-1) a graft copolymer obtained by polymerizing an aromatic vinyl monomer, optionally with other vinyl monomer, in the presence of a butadiene type rubbery polymer or (c-2) a graft copolymer obtained by polymerizing an aromatic vinyl monomer and a heterocyclic compound having a vinyl group and containing nitrogen as the hereto atom, optionally with other ethylenically unsaturated compound, in the presence of a butadiene type rubbery polymer, wherein at least one of the components (B) and (C) is a polymer of the nitrogen-containing heterocyclic compound, and the total amount of the components (A), (B) and (C) is 100 parts by weight.
A thermoplastic resin composition comprising (A) 10 to 60 parts by weight of a polyphenylene ether resin, (B) 20 to 70 parts by weight of an aromatic vinyl resin free of a nitrogen-containing heterocyclic compound and (C) 10 to 60 parts by weight of a graft copolymer obtained by polymerizing an aromatic vinyl monomer and a heterocyclic compound having a vinyl group and containing nitrogen as the hetero atom, optionally with at least one ethylenically unsaturated compound selected from the group consisting of methacrylic acid esters, acrylic acid esters, maleimide derivatives and vinyl group-containing nitrogen bases, in the presence of a butadiene based rubbery polymer, wherein the total amount of the components (A), (B) and (C) is 100 parts by weight.
