ANTISTATIC POLYCARBONATE RESIN COMPOSITION AND MOLDING THEREOF

PROBLEM TO BE SOLVED: To provide an antistatic polycarbonate resin composition having excellent antistaticity, weather resistance, hue, heat resistance in molding, transparency, and impact resistance, and moldings composed of the composition, particularly transparent members for vehicles. SOLUTION: The antistatic polycarbonate resin composition includes 100 pts.wt. of a polycarbonate resin (component A), 0.01-4 pts.wt. of a low molecular weight sulfonate (component B), and 0.05-3 pts.wt. of an ultraviolet absorbent (component C). The component C is at least one compound selected from the group consisting of benzotriazole-based, benzotriazine-based, benzoxadine-based, 2-cyanoacrylic and benzophenone-based compounds, and has a 10% weight reduction temperature of ≥280°C as measured by TGA (thermogravimetric analysis). Preferably, the antistatic polycarbonate resin composition further includes 0.01-5 pts.wt. of a polyether ester having a sulfonate group and/or polyester having a sulfonate group (component D). More preferably, the antistatic polycarbonate resin composition includes 0.001-0.5 pts.wt. of a phosphate (component E). Much more preferably, the antistatic polycarbonate resin composition includes a hindered phenolic antioxidant (component F), and a phosphite antioxidant (component G). The moldings, particularly transparent members for vehicles, transparent members for game macines, and transparent sheet members are molded from the composition. COPYRIGHT: (C)2011,JPO&INPIT
