摘要： A thermoplastic resin composition of the present invention comprises: approximately 100 parts by weight of polycarbonate resin including approximately 70-95 wt% of linear polycarbonate resin and approximately 5-30 wt% of branched polycarbonate resin; approximately 10-30 parts by weight of a phosphorus-based flame retardant; approximately 0.01-0.5 parts by weight of a fluoropolymer capsulated with methyl methacrylate; and approximately 0.01-0.5 parts by weight of an alkoxysilane-based compound. The thermoplastic resin composition has excellent transparency, flame retardancy, impact resistance, balance of physical properties thereof, and the like.

摘要： A method for producing flame retardant polycarbonate resin composition pellets using a twin screw extruder, wherein,
from 30 to 85 mass% of resin pellets (A) in which a polycarbonate resin having 2.7 to 3.4 of Mw/Mn at more than 40 mass% in the pellets (A); not less than 5 mass% and less than 25 mass% of phosphorus flame retardant (B); 0.1 to 1.0 mass% of polytetrafluoroethylene (C); 0 to 50 mass% of polycarbonate resin flake (D); 0 to 30 mass% of styrenic copolymer resin (E); and 0 to 15 mass% of another additive (F) other than the (B) and (C) are kneaded by the twin screw extruder in a kneading section with a screw configuration consisting of two or more selected from R kneading disc, N kneading disc, L kneading disc, L screw, sealing ring, mixing screw and rotor screw, at a screw rotation speed of 370 to 830 rpm, with the torque density applied to a screw shaft being 6.0 to 16.0 Nm/cm3, and are extruded as a strand from the extruder and then cut.
