A flame retardant thermoplastic resin composition includes (a) a polycarbonate resin, (b) an impact modifier, and (c) resorcinol bis(diphenyl phosphate). The impact modifier includes (b1) a large rubber particle-modified vinyl graft copolymer wherein the rubber particle has an average particle diameter of about 0.3 to about 0.7 &#x3bc;m, and (b2) a small rubber particle-modified graft copolymer wherein the rubber particle has an average particle diameter of about 0.05 to about 0.27 &#x3bc;m. The flame retardant thermoplastic resin composition can have excellent flowability, mold formability, flame retardancy, impact strength, and gloss characteristics.

Flame retardant thermoplastic resin composition

An acrylate-aromatic vinyl-vinyl cyanide resin composition having thermochromic resistance at high temperatures is provided. The resin composition includes: (A) about 20 to about 50% by weight of acrylic graft copolymer; (B) about 20 to about 50% by weight of two types of aromatic vinyl-vinyl cyanide copolymers with different molecular weights; and (C) about 30 to about 50% by weight of alpha-methyl styrene terpolymer.

Acrylate-styrene-acrylonitrile resin composition having thermochromic resistance at high temperatures

A polycarbonate resin composition includes about 100 parts by weight of a base resin including about 45 to about 86 parts by weight of a polycarbonate resin (A), about 10 to about 45 parts by weight of a polysiloxane-polycarbonate copolymer (B) and about 4 to about 10 parts by weight of an aromatic vinyl graft copolymer (C), about 0.03 to about 5 parts by weight of a sulfonate flame retardant (D) based on about 100 parts by weight of the base resin, and about 1 to about 10 parts by weight of a polycaprolactone polymer (E) based on about 100 parts by weight of the base resin.
