FLAME RETARDANT POLYCARBONATE WITH GOOD MECHANICAL PROPERTIES AND MELT STABILITY

摘要

Mo-1694 PC-025 FLAME RETARDANT AROMATIC POLYCARBONATE WITH GOOD MECHANICAL PROPERTIES AND MELT STABILITY The present invention is concerned with flame retardant polycarbonate compositions having good mechanical properties and melt stability. These properties are achieved by adding small amounts of a fibril forming polytetrafluoroethylene and an alkali metal salt of an inorganic acid to a thermoplastic aromatic polycarbonate. In a preferred embodiment, a small amount of aromatically bound chlorine or bromine is also added to further enhance the flame retardance. PC-025
