Abstract
A process is provided for making a flame composition. The process involves (a) mechanically dry blending (i) a tetrafluoroethylene polymer, preferably in powder form, and (ii) a first thermoplastic resin, preferably a vinyl aromatic resin to form a preblend composition and (b) admixing the preblend composition with a thermoplastic resin and a flame retardant to form the thermoplastic resin. The process provides enhanced levels of falling dart impact strength in articles molded from the thermoplastic composition.
