Abstract: The invention relates to flame retardant compositions, wherein salts of selected aromatic sulphonic acids are present in a polycarbonate substrate. The compositions attain the desirable V-0 rating, according to UL-94 (Underwriter's Laboratories Subject 94) and other excellent ratings in related test methods while preserving the excellent mechanical, chemical and thermal properties of polycarbonates, such as light transparency.
