| description | PROBLEM TO BE SOLVED: To provide a polycarbonate resin composition excellent in transparency, small in double refraction and excellent in impact resistance and external appearance of a molded article.SOLUTION: There is provided a polycarbonate resin composition containing, based on 100 pts.mass of polycarbonate resin (A) containing a bisphenol A-type polycarbonate resin (A1) of 80 to 99 mass% and a polycarbonate resin (A2) having a specific structural unit represented by the general formula (1) of 1 to 20 mass%, a styrene resin having a higher refractive index than that of the polycarbonate resin (A) (B1) and a styrene resin having a lower refractive index than that of the polycarbonate resin (A) (B2) of 40 to 100 pts.mass as total of (B1) and (B2) and high impact polystyrene (C) of 0.1 to 5 pts.mass.SELECTED DRAWING: None
【課題】透明性に優れ、複屈折が小さく耐衝撃性と成形品の外観に優れたポリカーボネート樹脂組成物を提供する。【解決手段】ビスフェノールＡ型ポリカーボネート樹脂（Ａ１）８０〜９９質量％及び一般式（１）で表される特定の構造単位を有するポリカーボネート樹脂（Ａ２）１〜２０質量％を含有するポリカーボネート樹脂（Ａ）１００質量部に対し、ポリカーボネート樹脂（Ａ）の屈折率より高い屈折率を有するスチレン系樹脂（Ｂ１）とポリカーボネート樹脂（Ａ）の屈折率より低い屈折率を有するスチレン系樹脂（Ｂ２）を（Ｂ１）と（Ｂ２）の合計で４０〜１００質量部及びハイインパクトポリスチレン（Ｃ）を０．１〜５質量部含有することを特徴とするポリカーボネート樹脂組成物。【選択図】なし |
