A thermoplastic resin composition of the present invention comprises: about 100 parts by weight of a polycarbonate resin; about 1 part by weight to about 5 parts by weight of a silicone-based rubber modified vinyl graft copolymer; and about 0.03 parts by weight to about 0.2 parts by weight of a metallic salt compound; wherein the metallic salt compound comprises a compound represented by the Formula 1, a compound represented by the Formula 2 and/or a compound represented by the Formula 3 as defined herein. The thermoplastic resin composition can have good properties in terms of impact resistance, impact resistance after ultrasonic welding, flame retardancy, heat resistance, and the like.

Thermoplastic resin composition and article produced therefrom

A thermoplastic resin composition comprises: about 100 parts by weight of a polycarbonate resin; about 50 parts by weight to about 250 parts by weight of a polyester resin; about 10 parts by weight to about 200 parts by weight of an aromatic polyphosphonate having a weight average molecular weight of about 65,000 g/mol to about 130,000 g/mol; and about 0.1 parts by weight to about 2 parts by weight of an organic acid comprising citric acid, lactic acid, malic acid, tartaric acid, and/or glycolic acid.

Thermoplastic polycarbonate resin composition including aromatic polyphosphonate and organic acid and article produced therefrom

A thermoplastic resin composition comprises about 100 parts by weight of a polycarbonate resin; and about 0.5 parts by weight to about 3 parts by weight of polystyrene-poly(methyl methacrylate) copolymer particles, wherein the polystyrene-poly(methyl methacrylate) copolymer particles include about 41 wt % to about 59 wt % of polystyrene and about 41 wt % to about 59 wt % of poly(methyl methacrylate) and have an average particle diameter of about 3 &#x3bc;m to about 9 &#x3bc;m and a coefficient of variation (CV) of about 20% to about 40%. The thermoplastic resin composition can have good properties in terms of light transmission, light diffusion and balance therebetween.

Thermoplastic resin composition and light diffusion sheet produced therefrom

A thermoplastic resin composition and a molded article formed of the same. The thermoplastic resin composition includes: about 100 parts by weight of a polycarbonate resin; about 5 to about 20 parts by weight of a rubber modified aromatic vinyl copolymer resin; about 0.5 to about 3 parts by weight of a maleic anhydride-grafted rubber polymer; about 50 to about 100 parts by weight of glass fibers; about 10 to about 30 parts by weight of barium sulfate; and about 5 to about 20 parts by weight of a phosphorus flame retardant. The thermoplastic resin composition can have high specific gravity and good properties in terms of impact resistance, weather resistance, flame retardancy, fluidity, and the like.
