Polycarbonate Resin Composition and Molded Article Produced Therefrom

摘要

The polycarbonate resin composition includes: a polycarbonate component, which includes an aromatic polycarbonate resin and a copolymerized polycarbonate resin including a repeat unit represented by Formula 1 and a repeat unit represented by Formula 2; and a flame retardant, and has a scratch width of about 310 μm or less as measured by Ball-type Scratch Profile (BSP) test; a pencil hardness rating of F or higher; a flame retardancy level of V-0 or higher as measured on a 2.0 mm thick specimen according to UL94; and a transmittance of about 80% or more as measured in accordance with ASTM D1003. The polycarbonate resin composition can exhibit excellent properties in terms of scratch resistance, flame retardancy and transparency.;wherein R1 and R2 are the same or different and are each independently substituted or unsubstituted C1 to C6 alkyl, and a and b are the same or different and are each independently an integer from 1 to 4.
