Abstract:
(EN) Provided is a polycarbonate-based resin composition containing 1-50 mass% of a polycarbonate-based resin (C) and 50-99 mass% of a polycarbonate-based resin (S) which contains: 0.1-100 mass% of a polycarbonate-polyorganosiloxane copolymer (A) containing a specific repeating unit-containing polycarbonate block (A-1) and a specific repeating unit-containing polyorganosiloxane block (A-2); and 0-99 mass% of an aromatic polycarbonate-based resin (B) other than the polycarbonate-polyorganosiloxane copolymer (A), the polycarbonate-based resin composition being characterized in that the average chain length of the polyorganosiloxane block (A-2) is at least 20 and less than 50, and the total light transmittance of a 3 mm plate thereof is at least 80%.
(FR) La présente invention concerne une composition de résine à base de polycarbonate contenant de 1 à 50 % en masse d’une résine à base de polycarbonate (C) et de 50 à 99 % en masse d’une résine à base de polycarbonate (S) qui contient : de 0,1 à 100 % en masse d’un copolymère de polycarbonate-polyorganosiloxane (A) contenant une séquence de polycarbonate contenant un motif de répétition spécifique (A-1) et une séquence de polyorganosiloxane contenant un motif de répétition spécifique (A-2) ; et de 0 à 99 % en masse d’une résine à base de polycarbonate aromatique (B) autre que le copolymère de polycarbonate-polyorganosiloxane (A), la composition de résine à base de polycarbonate étant caractérisée en ce que la longueur de chaîne moyenne de la séquence de polyorganosiloxane (A-2) est supérieure ou égale à 20 et inférieure à 50, et en ce que la transmittance totale de la lumière d’une plaque de 3 mm constituée de cette dernière est d’au moins 80 %.
(JA) 特定の繰り返し単位からなるポリカーボネートブロック(A-1)及び特定の繰り返し単位を含むポリオルガノシロキサンブロック(A-2)を含むポリカーボネート-ポリオルガノシロキサン共重合体(A)0.1質量%以上100質量%以下と、前記ポリカーボネート-ポリオルガノシロキサン共重合体(A)以外の芳香族ポリカーボネート系樹脂(B)0質量%以上99.9質量%以下とを含むポリカーボネート系樹脂(S)50質量%以上99質量%以下、及びポリエステル系樹脂(C)1質量%以上50質量%以下を含み、前記ポリオルガノシロキサンブロック(A-2)の平均鎖長が20以上50未満であり、3mmプレートの全光線透過率が80%以上であることを特徴とする、ポリカーボネート系樹脂組成物。
