PURPOSE: A flame retardant thermoplastic resin composition and a molded product prepared by using the composition are provided, to improve the impact resistance, the thermal stability, the workability and the appearance of the resin composition. CONSTITUTION: The thermoplastic resin composition comprises 100 parts by weight of a base resin comprising 45-95 parts by weight of a polycarbonate resin, 1-50 parts by weight of a rubber-modified graft copolymer, and 1-50 parts by weight of vinyl-based copolymers or their mixture; 1-30 parts by weight of a mixture comprising 1-50 wt% of a cyclic phosphazene oligomer compound represented by the formula 2 and 50-99 wt% of a phosphate compound represented by the formula 4; 0.5-15 parts by weight of talc with an average particle size of 0.1-50 micrometers; and 0.05-5 parts by weight of a fluorinated polyolefin-based resin with an average particle size of 0.05-1,000 micrometers and a density of 1.2-2.3 g/cm¬3, wherein R1 is an alkyl, aryl, alkyl-substituted aryl, arylalkyl, alkoxy, aryloxy, amino or hydroxy group (wherein the alkoxy or aryloxy group can be substituted with an alkyl, aryl, amino or hydroxy group); k and m are an integer of 0-10; R2 is an alkyl-substituted or unsubstituted dioxy aryl group of C6-C30; n is 0.3-3; R3, R4, R6 and R7 are respectively an alkyl-substituted or unsubstituted aryl group of C6-C20; R5 is an alkyl-substituted or unsubstituted aryl group of C6-C20; and an average number of / is 0-3. |
