Flame-resistant polycarbonate molding compositions containing halogen-free sulphonic acid salts of aromatic aldehydes or acetals of these aldehydes in quantities of about 0.005 to 10% relative to the total weight of the composition are disclosed. The compositions optionally further containing inorganic sulphates, exhibit flame retardance and little tendency to dripping in comparison to prior art compositions.
