摘要： A combination of a potassium salt of a perfluoroalkane sulfonate and a sodium salt of toluene sulfonic acid, preferably in the presence of an antidrip agent to provide high melt strength, act synergistically to provide flame-retarded polycarbonate compositions at low levels. Thus, a flame-retarded polycarbonate resin can be made by adding to the polycarbonate resin an effective flame-retardant amount of a potassium salt of a perfluoroalkane sulfonate and a sodium salt of toluene sulfonic acid. The two salts may be formulated in advance into an additive composition.

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 flameretarded 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.

摘要： Transparent polycarbonate compositions are made from polycarbonate produced in a base-catalyzed melt polymerization reaction to which an acidic quencher has been added in a 1 to 30-fold molar ratio with respect to the amount of initial basic catalyst; and a potassium perfluoralkane sulfonate and cyclic siloxane containing flameretardant component. In the composition these components work in combination such that the composition achieves a VO UL flammability rating at a thickness of 2.0 mm, preferably 1.6 mm, and has a haze of no more than 1%.
