ABSTRACT:
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.
