A thermoplastic resin composition is provided exhibiting enhanced levels of dart impact strength. The composition contains a vinyl aromatic resin, an increased tetrafluoroethylene polymer and a reduced level of metal salt of a fatty acid. The tetrafluoroethylene polymer is introduced into the composition in the form of a preblend of tetrafluoroethylene polymeric powder and a carrier material. The compositions are useful for making molded articles such as business machine housings. A method for making the composition is also provided.
