Abstract:
(EN) The main purpose of the present invention is to provide a multi-block copolymer composition having good elasticity and excellent stress relaxation properties, as well as low permanent elongation. The present invention achieves the above purpose by providing a multi-block copolymer composition obtained by a modification treatment, the composition including a block copolymer (B) into which a functional group is introduced that is capable of non-covalently bonding to a block copolymer (A), wherein the block copolymer (A) includes a block copolymer (A1) having a specific primary structure and a block copolymer (A2) having a specific primary structure, and the mass ratio (A1/A2) of the block copolymer (A1) and the block copolymer (A2) is 100/0 to 50/50.
(FR) L'objet principal de la présente invention est de fournir une composition de copolymère à blocs multiples présentant une bonne élasticité et d'excellentes propriétés de relaxation des contraintes, ainsi qu'un faible allongement permanent. La présente invention atteint l'objectif ci-dessus en fournissant une composition de copolymère à blocs multiples obtenue par un traitement de modification, la composition comprenant un copolymère à blocs (B) dans lequel est introduit un groupe fonctionnel qui est capable de se lier de manière non covalente à un copolymère à blocs (A), le copolymère à blocs (A) comprenant un copolymère à blocs (A1) ayant une structure primaire spécifique et un copolymère à blocs (A2) ayant une structure primaire spécifique, et le rapport de masse (A1/A2) du copolymère à blocs (A1) et du copolymère à blocs (A2) étant de 100/0 à 50/50.
(JA) 本発明は、弾性が良好で、応力緩和性に優れ、しかも永久伸びが小さいマルチブロック共重合体組成物を提供することを主目的とする。 本発明は、ブロック共重合体(A)に非共有結合可能な官能基が導入されてなるブロック共重合体(B)を含む、変性処理により得られるマルチブロック共重合体組成物であって、上記ブロック共重合体(A)が、特定の一次構造を有するブロック共重合体(A1)と、特定の一次構造を有するブロック共重合体(A2)とを含み、上記ブロック共重合体(A1)と上記ブロック共重合体(A2)との質量比(A1/A2)が100/0~50/50である、マルチブロック共重合体組成物を提供することにより、上記課題を解決する。
