Flame-retardant polycarbonate molding materials ii

Composition comprising

• A) 48-95 parts by weight of aromatic polycarbonate and/or aromatic polyestercarbonate,
• B) 1.0-20.0 parts by weight of rubber-modified graft polymer,
• C) 1.0-20.0 parts by weight of at least one cyclic phosphazene of formula (X):
• where
• k is 1 or an integer from 1 to 10, optionally a number from 1 to 8 and optionally 1 to 5,
• the trimer content (k=1) being from 60 to 98 mol %, based on component C,
• and
• R are in each case identical or different and are an amine radical, C1- to C8-alkyl in each case optionally halogenated, optionally with fluorine, preferably methyl, ethyl, propyl or butyl, C1- to C8-alkoxy, optionally methoxy, ethoxy, propoxy or butoxy, C5- to C6-cycloalkyl in each case optionally substituted by alkyl, preferably C1-C4-alkyl, and/or halogen, preferably chlorine and/or bromine, C6- to C20-aryloxy in each case optionally substituted by alkyl, preferably C1-C4-alkyl, and/or halogen, optionally chlorine or bromine, and/or hydroxyl, preferably phenoxy or naphthyloxy, C7- to C12-aralkyl in each case optionally substituted by alkyl, preferably C1-C4-alkyl, and/or halogen, optionally chlorine and/or bromine, optionally phenyl-C1-C4-alkyl, or a halogen radical, optionally chlorine, or an OH radical,
• D) 1.0-7.0 parts by weight of at least one phosphorus-containing organic flameproofing agent other than C,
• E) 0-15.0 parts by weight of one or more rubber-free vinyl (co)polymer or polyalkylene terephthalates,
• F) 0-15.0 parts by weight of one or more additives and
• G) 0.05 to 5.00 parts by weight of antidripping agent,
• all the parts by weight optionally being scaled so that the sum of the parts by weight of all the components A+B+C+D+E+F+G in the composition is 100, and
• at least 50% of the amount of phosphorus in the composition originating from component C.
