主权项 1. Composition comprising A) from 80 to 98 parts by weight of aromatic polycarbonate and/or aromatic polyester carbonate, B) from 0.5 to 6.0 parts by weight of rubber-modified graft polymer, C) from 0.8 to 5.0 parts by weight of at least one cyclic phosphazene according to formula (X)wherein k represents 1 or an integer from 1 to 10, wherein the trimer content (l=1) is from 60 to 98 mol %, wherein the content of higher oligomeric phosphazenes (k=3, 4, 5, 6 and 7) is from 5 to 20 mol %, in each case based on component C,and wherein R is in each case identical or different and represents an amine radical; C1- to C8-alkyl, each optionally halogenated; C1- to C8-alkoxy; C5- to C6-cycloalkyl, each optionally substituted by alkyl and/or by halogen; C6- to C20-aryloxy each optionally substituted by alkyl, and/or by halogen, and/or by hydroxy; C7- to C12-aralkyl, each optionally substituted by alkyl, and/or by halogen; or a halogen radical; or an OH radical, D) from 0 to 5.0 parts by weight of rubber-free vinyl (co)polymer or polyalkylene terephthalate, E) from 0 to 15.0 parts by weight of one or more additives, F) from 0.05 to 1.00 part by weight, of one or more antidripping agents,wherein all the parts by weight are optionally normalised that the sum of the parts by weight of all the components A+B+C+D+E+F in the composition is 100.
