Abstract: front page image
(EN)A laminate comprising a base layer, an adhesive layer, and a hydrogenated copolymer composition layer which is bonded to the base layer via the adhesive layer is characterized in that the hydrogenated copolymer composition layer is composed of a hydrogenated copolymer (I) and a rubbery polymer (II) and the hydrogenated copolymer (I) is obtained by hydrogenating a conjugated diene-vinyl aromatic copolymer and has the following features (1)-(4): (1) the content of the vinyl aromatic monomer unit is more than 50 weight% but not more than 90 weight%; (2) the content of the vinyl aromatic block is not more than 40 weight%; (3) the weight-average molecular weight of the copolymer (I) is from 50,000 to 1,000,000; and (4) the hydrogenation ratio of the double bond of the conjugated diene monomer unit is not less than 70%.
(FR)L'invention porte sur un laminé comprenant: une couche de base, une couche adhésive, et une couche d'une composition de copolymère hydrogéné fixée à la couche de base par l'intermédiaire de la couche adhésive. Ledit laminé se caractérise en ce que: la couche de composition de copolymère hydrogéné comprend: un polymère caoutchouteux (II), et un copolymère hydrogéné (I) obtenu par hydrogénation d'un copolymère conjugué de diène/vinyle, et présentant les caractéristiques suivantes: (1) la teneur en unités de monomère aromatique de vinyle est de plus de 50 % et de moins de 90 %; (2) la teneur en blocs aromatiques de vinyle est inférieure à 40 %; (3) la masse moléculaire moyenne en poids du copolymère (I) est comprise entre 50.000 et 1.000.000, et (4) le rapport d'hydrogénation de la double liaison de l'unité conjuguée diène/monomère n'est pas inférieur à 70 %.
