This invention is concerned with a new class of flame retardant polycarbonate compositions. More particularly, the invention is concerned with an admixture of an aromatic polycarbonate and a flame retardant additive selected from an alkali or alkaline earth metal salt of an inorganic sulfur compound. The flame retardant polycarbonates can be molded or formed into fire-retardant articles, such as films, sheets, fibers, laminates, or reinforced plastics by conventional techniques. |
