Title
(EN) RESIN COMPOSITION AND RESIN PRODUCT
(FR) COMPOSITION ET PRODUIT DE RÉSINE
(JA) 樹脂組成物及び樹脂製品
Abstract
(EN) The present invention addresses the problem of providing: a resin composition which is suitable as a starting material for 3D printers, and which achieves a good balance between formability and fracture characteristics; and a resin product which uses this resin composition and has excellent fracture characteristics. Solutions for this problem are: a resin composition which is characterized by containing (A) a copolymer that comprises a non-conjugated olefin unit, a conjugated diene unit and an aromatic vinyl unit, (B) a thermoplastic resin and/or (C) a thermoplastic elastomer, and which is also characterized in that the copolymer (A) has a melting point of 55°C or higher; and a resin product which is characterized by the use of this resin composition.
(FR) La présente invention a pour but de fournir : une composition de résine qui soit appropriée en tant que matériau de départ pour des imprimantes 3D et qui permette un bon équilibre entre l'aptitude au formage et les caractéristiques de fracture ; un produit de résine qui utilise cette composition de résine et qui présente d'excellentes caractéristiques de fracture. Pour atteindre ce but, l'invention concerne : une composition de résine qui est caractérisée en ce qu'elle contient (A) un copolymère qui comporte un motif oléfine non conjuguée, un motif diène conjugué et un motif vinyle aromatique, (B) une résine thermoplastique et/ou (C) un élastomère thermoplastique, et qui est également caractérisée en ce que le copolymère (A) possède un point de fusion de 55 °C ou plus ; un produit de résine qui est caractérisé par l'utilisation de cette composition de résine.
(JA) 本発明の課題は、３次元プリンタ用の原材料として好適で、成形性と破壊特性とを両立した樹脂組成物、並びに、かかる樹脂組成物を用いた、破壊特性に優れる樹脂製品を提供することであり、その解決手段は、非共役オレフィン単位と、共役ジエン単位と、芳香族ビニル単位と、を含有する共重合体（Ａ）と、熱可塑性樹脂（Ｂ）及び／又は熱可塑性エラストマー（Ｃ）と、を含有し、前記共重合体（Ａ）は、融点が５５℃以上であることを特徴とする、樹脂組成物、並びに、該樹脂組成物を用いたことを特徴とする、樹脂製品である。
