Abstract: The present invention relates to moulding compositions of polycarbonates and graft polymers and optionally further additives and components, which have, in addition to a high resistance to chemicals, a good resistance to heat, in particular a low tendency towards yellowing and a low tendency towards degradation when exposed to heat.In a particular, flameproofed embodiment, the after-burn time in a UL94 classification is furthermore reduced.
