<p>PURPOSE: A poly carbonate resin composition is provided to have excellent physical balance about coloring property, impact resistance, heat resistance, scratch resistance, transparency and flame retardancy, thereby suitable for flame retardant non-coating material. CONSTITUTION: A poly carbonate resin composition comprises 100.0 parts by weight of a base resin, 1-50 parts by weight of phosphorous-based flame retardant. The base resin comprises 10-89 weight% of a polycarbonate resin, 10-89 weight% of a polycarbonate-polysiloxane copolymer, and 1-70 weight% of a modified (meth)acrylic copolymer resin. The polycarbonate-polysiloxane copolymer comprises 1-9 weight% of a polycarbonate block and 1-99 weight% of a polysiloxane block. The refractive index of the modified (meth)acrylic resin is 1.495-1.590.</p> |
