    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.
