    • Copolycarbonates are provided which have improved flame resistance and a reduced tendency to drip when flamed based on aromatic dihydroxy compounds, characterized in that they contain, besides the carbonate carbonyl radical, radicals derived by the removal of the hydroxyl hydrogen atoms from dihydroxy-diaryl compounds, radicals derived by the removal of the hydroxyl hydrogen atoms from nuclear halogenated by-hydroxyaryl compounds and bivalent radicals derived by the removal of the hydroxyl hydrogen atoms from the bis-hydroxy-sulfones of the formula (1)

      AND/OR OF THE FORMULA (2)

      IN WHICH Z is phenylene, diphenylene, naphthylene or a bivalent radical of formula (3)

      IN WHICH R can be -O-, alkylene, alkylidene cycloalkylene, cycloalkylidene, SO2, SO, S or >CO, the amount of the sulfone being 0.1 mol% to 10 mol%, preferably 0.5 mol% to 5 mol%, based on the total amount of the di- and bis-hydroxy-compounds mentioned above.
