FLAME RETARDANT THERMOPLASTIC COMPOSITION CONTAINING AROMATIC POLYCARBONATE RESINS AND A RUBBER MODIFIED GRAFT COPOLYMER

摘要

Abstract of the Disclosure A thermoplastic composition is providedexhibiting reduced viscosity and desirableheat/humidity aging properties. The compositionincludes (a) an aromatic polycarbonate resin, (b) avinyl aromatic-vinyl cyanide rigid resin, (c) a graftcopolymer having (i) a rubber substrate, (ii) asuperstrate grafted to the substrate and (iii) a [err]to [err] polyacid, (d) a phosphate flame retardant, and(e) a tetrafluoroethylene polymer. The compositionis useful for making molded articles such as businessmachine housings.341062
