<p>The invention relates to impact-modified polycarbonate compositions and to moulding materials comprising A) aromatic polycarbonate or aromatic polyestercarbonate or mixtures thereof, B) a mixture comprising Ba) at least one graft polymer prepared in emulsion polymerization and Bb) at least one carboxylate salt, where this mixture slurried as a 10% by weight suspension in distilled water has a pH of >7, C) at least one acidic phosphorus compound with at least one P-OH functionality, which feature an improved combination of hydrolysis stability and thermal stability compared to the prior art, and which are suitable for manufacture of injection-moulded components which display a good low-temperature toughness and - even in the case of critical processing operations (high processing temperatures) - still have good stress-cracking resistance under the influence of chemicals.</p> |
