PROBLEM TO BE SOLVED: To obtain a fireproof thermoplastic molding composition excellent in stress cracking resistance, etc. by including six kinds of components such as an aromatic polycarbonate, a styrene-containing copolymer and a styrene- containing graft copolymer in a specific proportion. SOLUTION: This composition is obtained by including (A) 40-90 pts.wt. of an aromatic polycarbonate, (B) 5-30 pts.wt. of a styrene-containing copolymer, (C) 5-30 pts.wt. of a styrene-containing graft copolymer, (D) (i) a monophosphorus compound and/or an oligomer type phosphorus compound in an amount of 1-25 pts.wt. based on 100 pts.wt. of the total amount of the components A to C, (E) a silicon compound represented by the formula ((n) and (m) are each 5-8; and (x) and (y) are each 1-5) in an amount of 0.5-15 pts.wt. based on 100 pts.wt. of the total amount of the components A to C, (F) a tetrafluoroethylene polymer in an amount of 0.05-5 pts.wt. based on 100 pts.wt. of the total amount of the components A to C and, as necessary, (G) an inorganic compound acting as a flameproof synergist such as talc, an antioxidant, a dye, a pigment, a brightener, etc. |
