Title: FLAME-RETARDANT AROMATIC POLYCARBONATE RESIN COMPOSITION
Abstract:
A flame-retardant aromatic polycarbonate resin composition which comprises 100 parts by weight of an aromatic polycarbonate (A), 0.01 to 0.5 parts by weight of metal oxide particles having a branched structure (metal oxide particle aggregates and/or metal oxide particle agglomerates) (B), 0.0001 to 0.2 parts by weight of an alkali metal salt of an organic sulfonic acid (C), and 0.01 to 0.5 parts by weight of a fluoropolymer (D), characterized in that the metal oxide particles (B) have been dispersed in a mixture of the aromatic polycarbonate (A), metal oxide particles (B), and organic sulfonic acid alkali metal salt (C) and at least 70% of the metal oxide particles (B) have a particle diameter in the range of 10 to 200 nm.
