Abstract:
A flame-retardant thermoplastic moulding composition containingA 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 <10Â° 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) â€ƒwherein 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) â€ƒwherein 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.
