    摘要： A flame resistant thermoplastic molding composition is disclosed. The composition contains a mixture of two aromatic polycarbonates having differing solution viscosities, a vinyl(co)polymer made from at least two ethylenically unsaturated monomers, a graft polymer obtainable by graft polymerization of at least two monomers selected from chloroprene, 1,3-butadiene, isoprene, styrene, acrylonitrile, ethylene, propylene, vinyl acetate and (meth)acrylates with 1 to 18 carbon atoms in the alcohol component, a phosphorous compound, a fluorinated polyolefin and an inorganic compound with an average particle size no greater than 200 nm. The inventive composition is additionally characterized in its improved stress cracking resistance.
