Zusammenfassung:The invention relates to polymer mixtures which comprise a polyalkylene phthalate and an aromatic polycarbonate and/or a brominated aromatic carbonate oligomer, polymer or copolymer. It has been found that zinc or calcium hydrogen phosphates are good transesterification inhibitors. An important advantage of the said inhibitors is that they do not condense or hardly condense to polyphosphates and that they do not negatively influence the impact strength of the polymer mixture.
