Flame-resistant polycarbonate ABS moulding compounds

A flame-retardant thermoplastic moulding composition containing

• A 5 to 95 parts by weight of an aromatic polycarbonate or polyestercarbonate
• B. 0.5 to 60 parts by weight of at least one graft polymer of
• B.1 5 to 95 wt. % of one or more vinyl monomers on
• B.2 95 to 5 wt. % of one or more graft substrates with a glass transition temperature <10° C.
• C. 0 to 45 parts by weight of a thermoplastic vinyl copolymer,
• D. 0.5 to 20 parts by weight of at least one phosphorus compound of general formula (I)
• wherein
• R1, R2, R3, and R4, independently of each other, each represent C1- to C8-alkyl, C5- to C6-cycloalkyl, C6- to C20-aryl or C7- to C12-aralkyl, which are optionally halogenated,
• n represents 0 or 1, which are independent of each other,
• N is an average number from 5 to 30,
• X represents a mono- or polynuclear aromatic radical containing 6 to 30 carbon atoms,
• E 0 to 5 parts by weight of a fluorinated polyolefin, and
• F.1 0.5 to 40 parts by weight of a finely divided inorganic powder with an average particle diameter of less than or equal to 200 nm, and/or
• F.2 05 to 20 parts by weight of a monophosphorus compound of formula (IA)
• wherein
• R11, R12 and R13, independently of each other, denote C1-C8-alkyl, which is optionally halogenated, or C6-C20-aryl, which is optionally halogenated,
• m1 denotes 0 or 1, and
• n1 denotes 0 or 1,
• wherein the sum of all the parts by weight of all the components is 100.
