The present invention relates to polycarbonate compositions comprising A) an aromatic polycarbonate and/or an aromatic polyester carbonate, B) a graft polymer obtained by the co-precipitation of a mixture of at least two graft polymer dispersions B.1 and B.2, characterized in that the production of graft polymer component B.1 is performed using at least one redox system as an initiator and that the production of graft polymer component B.2 is performed using at least one persulfate compound as an initiator, and C) optionally vinyl(co)polymer and/or polyalkylene terephthalate, D) optionally flame retardants containing phosphorous, E) at least one phenolic antioxidant, F) optionally neutral co-stabilizers (synergists) containing phosphorous or sulfur and G) optionally additives characterized by an optimum combination of good hydrolysis resistance and a light natural colour, and to the use of the polycarbonate compositions for the production of molded bodies, and to said molded bodies.
