This invention relates to ignition resistant thermoplastic polymer compositions which are mixtures of (i) a non-carbonate polymer such as a polyester terephthalate, a polyacetal, or a polymethylmethacrylate, (ii) a carbonate polymer, or (3) a blend of (i) and (ii) with a high elastic memory polytetrafluoroethylene, an organic phosphate, and a metal salt of an inorganic acid. The present invention represents an improvement over the prior art in that the need for glass fibers and halogenated compounds has been eliminated. |
