IMPACT-MODIFIED POLYCARBONATE COMPOSITIONS CONTAINING ACIDIC PHOSPHORUS COMPOUNDS AND COMPRISING BASICALLY PRECIPITATED EMULSION GRAFT POLYMER

The invention relates to impact-modified polycarbonate compositions and moulding compositions comprising A) aromatic polycarbonate or aromatic polyester carbonate or mixtures of these, B) a mixture containing Ba) at least one graft polymer prepared in emulsion polymerization and Bb) at least one carboxylate salt, wherein this mixture, suspended as a 10 wt.% strength suspension in distilled water, has a pH of > 7, C) at least one acidic phosphorus compound with at least one P-OH functionality, which are distinguished compared with the prior art by an improved combination of stability to hydrolysis and heat stability, and which are suitable for production of injection-moulded components which have a good toughness at low temperatures and - even with critical processing conditions (high processing temperatures) - still have a good resistance to stress cracking under the influence of chemicals.
