Abstract
(EN) Disclosed are a thermoplastic elastomer composition comprising 100 parts by mass of a powdery hydrogenated block copolymer (a), which is obtained by hydrogenating a block copolymer comprising a polymer block (A) containing a structural unit originating in an aromatic vinyl compound and another polymer block (B) containing a structural unit originating in isoprene or an isoprene/butadiene mixture and containing a 3,4-bond unit and a 1,2-bond unit in a total amount of 45% or more, and has a peak top molecular weight (Mp), determined on polystyrene equivalent basis by gel permeation chromatography, of 250,000-500,000 and a bulk density of 0.10-0.40 g/ml; 10-300 parts by mass of a softening agent (b); and 5-200 parts by mass of a polyolefin resin (c), and a molded article and a sealing material for medical use each comprising said thermoplastic elastomer composition.
(FR) La présente invention concerne une composition élastomère thermoplastique comprenant 100 parties en masse d'un copolymère séquencé hydrogéné pulvérulent (a), qui est obtenu par hydrogénation d'un copolymère séquencé comprenant une séquence de polymère (A) contenant un unité structurale provenant d'un composé vinylique aromatique et une autre séquence de polymère (B) contenant une unité structurale provenant de l'isoprène ou un mélange isoprène/butadiène et contenant une unité de liaison 3,4 et une unité de liaison 1,2 en une quantité totale de 45 % ou plus, et a un poids moléculaire maximal (Mp), déterminé sur une base d'équivalents de polystyrène par chromatographie de perméation de gel, de 250 000 à 500 000 et une densité apparente de 0,10 à 0,40 g/ml ; de 10 à 300 parties en masse d'un agent plastifiant (b) ; et de 5 à 200 parties en masse d'une résine polyoléfine (c), et un article moulé et un matériau de scellage pour utilisation médicale comprenant chacun ladite composition élastomère thermoplastique.
