Disclosed are polycarbonate compositions which exhibit high levels of flame retardance and excellent physical properties which do not contain alkali metal salts of perfluoro alkane sulfonates. Disclosed are methods of preparing such compositions. Disclosed are structures prepared from the disclosed compositions. The compositions comprise: a) at least one polycarbonate polymer; b) an impact modifier comprising a silicone core; and c) a phosphazene-based flame retardant. The compositions may comprise a polyarylate, or at least a portion of the at least one polycarbonate is a high temperature polycarbonate. The compositions may comprise one or more carbon based particulates, metal particulates or metal oxide particulates. The compositions may comprise post-consumer recycled polycarbonates.
