THERMOPLASTIC RESIN COMPOSITION AND MOLDED BODY

To provide a thermoplastic resin composition having excellent heat stability and impact resistance while maintaining transparency and to provide a molded body having excellent impact resistance and heat resistance composed of the composition.SOLUTION: There is provided a thermoplastic resin composition having a phase separation structure in which a dispersion phase is contained in a continuous phase, a polycarbonate resin (A) containing 50 mol% or more of a structural unit derived from a dihydroxy compound represented by the following formula (1) is contained in the continuous phase and a polycarbonate resin (B) having a glass transition temperature (TgB) lower than the glass transition temperature (TgA) of the polycarbonate resin (A) and a rubbery elastic component(C) are contained in the dispersion phase. (wherein, a bond represented by a wavy line represents a wedge shaped bond of a solid line or a broken line.)SELECTED DRAWING: Figure 1 【課題】本発明は、透明性を維持しつつ、熱安定性及び耐衝撃性に優れた熱可塑性樹脂組成物、及び、該組成物からなる、耐衝撃性及び耐熱性に優れた成形体を提供することを目的とする。【解決手段】連続相中に分散相が含まれる相分離構造を有し、該連続相に、下記式（１）で表されるジヒドロキシ化合物に由来する構造単位を５０ｍｏｌ％以上含むポリカーボネート樹脂（Ａ）が含まれ、該分散相に、該ポリカーボネート樹脂（Ａ）のガラス転移温度（ＴｇＡ）よりも低いガラス転移温度（ＴｇＢ）を有するポリカーボネート樹脂（Ｂ）と、ゴム質弾性成分（Ｃ）とが含まれる、熱可塑性樹脂組成物。TIFF2023148429000012.tif35170（式（１）中、波線で表される結合は、実線又は破線のくさび形結合を表す。）【選択図】図１
