    摘要: Improved fire-retarded properties can be imparted to polycarbonate resin composition by incorporating into the polycarbonate a fire-retardant component containing a perfluoroallkane sulfonate such as potassium perfluorobutane sulfonate and a cyclic siloxane such as octaphenylcyclotetrasiloxane. The fire-retardant component is suitably added at levels to form a polycarbonate composition in which the perfluoroalkane sulfonate is present in an amount of from 0.02 to 0.1 phr relative to the composition as a whole, and the cyclic siloxane is present in an amount of at least 0.02 relative to the composition as a whole.

    摘要: It has now been surprisingly found that addition of a phosphorous-containing oxy acid to a glass-filled polycarbonate composition substantially improves its fire retardant performance. Thus, the present invention provides a method for making a flame-retarded glass-filled polycarbonate resin comprising adding to the resin an effective flame-retardant amount of a phosphorous-containing oxy acid. Where appropriate, the melt strength of the polycarbonate is enhanced by the addition of an antidrip agent and the performance can be further enhanced by the addition of a flame retardant. Use of such a composition results in superior fire-retardant performance.
