Abstract:
(EN) [PROBLEM] To provide a thermoplastic resin composition capable of providing a moulded article which suppresses the occurrence of rattling noise and preferably has high rigidity. [SOLUTION] Provided is a thermoplastic resin composition that comprises a rubber-reinforced resin (A). The rubber-reinforced resin (A) comprises: a rubber portion (a1) including a rubber portion derived from a block copolymer, or hydrogenated product thereof; and a resin portion (a2) which includes a structural unit derived from an aromatic vinyl compound. The block copolymer includes: a block (I) which comprises a structural unit derived from an aromatic vinyl compound; and a block (II) which comprises a structural unit derived from isoprene or from isoprene and butadiene, and has a tanδ primary dispersion peak at no less than 0°C. The thermoplastic resin composition has a maximum sound pressure value of no more than 3.0 Pa/N over a frequency range of 20–20,000Hz measured under predetermined conditions.
(FR) Le problème décrit par la présente invention est de fournir une composition de résine thermoplastique capable de fournir un article moulé qui supprime l'apparition de bruit de cliquetis et présente de préférence une rigidité élevée. La solution selon l'invention porte sur une composition de résine thermoplastique qui comprend une résine renforcée par du caoutchouc (A). La résine renforcée par du caoutchouc (A) comprend : une partie caoutchouc (a1) comprenant une partie caoutchouc dérivée d'un copolymère séquencé, ou un produit hydrogéné de celui-ci ; et une partie résine (a2) qui comprend un motif structural dérivé d'un composé vinylique aromatique. Le copolymère séquencé comprend : un bloc (I) qui comprend un motif structural dérivé d'un composé vinylique aromatique ; et un bloc (II) qui comprend un motif structural dérivé d'isoprène ou d'isoprène et de butadiène, et a un pic de dispersion primaire tanδ à pas moins de 0 °C. La composition de résine thermoplastique a une valeur de pression sonore maximale ne dépassant pas 3,0 Pa/N sur une plage de fréquences de 20 à 20 000 Hz mesurée dans des conditions prédéfinies.
(JA) 【課題】打音の発生が抑制され、好ましくは高い剛性を備えた成形品を提供し得る熱可塑性樹脂組成物を提供する。 【解決手段】 芳香族ビニル系化合物に由来する構造単位を備えたブロック(I)と、イソプレンまたはイソプレン及びブタジエンに由来する構造単位を備え、0℃以上にtanδの主分散のピークを有するブロック(II)とを含むブロック共重合体またはその水素添加物に由来するゴム質部分を含むゴム質部分(a1)と、芳香族ビニル化合物に由来する構造単位を含む樹脂部分(a2)とを有するゴム強化樹脂(A)を含み、所定の条件で測定された20~20,000Hzの周波数域の音圧の最大値が3.0Pa/N以下である熱可塑性樹脂組成物。
