Claim:
1. A composition comprising A) from 10 to 99 parts by weight, in each case based on the entirety of components A+B+C, of aromatic polycarbonate and/or aromatic polyester carbonate, B) from 1 to 35 parts by weight, in each case based on the entirety of components A+B+C, of rubber-modified graft polymer of C) from 0 to 40 parts by weight, in each case based on the entirety of components A+B+C, of resinous, thermoplastic and rubber-free vinyl (co)polymer and/or polyalkylene terephthalate, D) from 0 to 50 parts by weight, in each case based on the entirety of components A+B+C, of phosphorus-containing flame retardant, E) from 0 to 1.0 part by weight, in each case based on the entirety of components A+B+C, of acidic additives and F) from 0 to 50 parts by weight, in each case based on the entirety of components A+B+C, of additional substances, wherein component B is obtained by reacting component B.1 with the graft base B.2 by emulsion polymerisation, with the proviso that, in the case of compositions that are free of components D) and E), the pH of the graft polymer dispersion during a precipitation step is less than 7, and the graft polymer is precipitated from the dispersion by addition of magnesium sulphate, where the emulsifier or emulsifiers and magnesium sulphate remain in component B.
