The invention discloses a
polycarbonate composition. The
polycarbonate composition comprises the following components including, by weight, a, 29.9-79.9 parts of
polycarbonate, b, 8.1-50.1 parts of a
graft polymer, c, 4.8-24.8 parts of a
fire retardant and d, 0-9.9 parts of other auxiliaries; the sum of the parts by weight of the four components including the a, the b, the c and the d is 100 parts, and the composition is based on the fact that the content of
phosphorus oxychloride in the total weight of the polycarbonate composition is less than or equal to 80 ppm and lager than or equal to 0.1 ppm. According to the polycarbonate composition, in the polycarbonate composition formula, on the basis that when the content of the tested
phosphorus oxychloride in the total weight of the polycarbonate composition does not exceed 80 ppm, the generation of stable compounds such as
phosphoric acid and
polymetaphosphate is facilitated by the trace level reserved
phosphorus oxychloride, the generation of carbon
layers is further promoted, meanwhile, the dispersing of
phosphorus containing the
fire retardant in the composition is improved, finally, the
fire resistance and the melt stability of the polycarbonate composition can be evidently improved, and in addition, the polycarbonate composition is particularly suitable for occasions with high using environment requirements.
