(JA) 光学フィルム
Abstract:
(EN) An optical film which is formed from a thermoplastic resin, and wherein: the thermoplastic resin contains a hydrogenated block copolymer (G) that contains two or more polymer blocks (D) per molecule, said polymer blocks (D) being mainly composed of a cyclic hydrocarbon group-containing compound hydride unit (I) and one or more polymer blocks (E) per molecule, said polymer blocks (E) being mainly composed of a chain hydrocarbon compound hydride unit (II) or a combination of the unit (I) and the unit (II); and the thermoplastic resin satisfies G"/G' > 0.95 or (η|ε=2 - η|ε=1) > -1.0 × 104 Pa·s. In the formula, G' represents the storage elastic modulus of the thermoplastic resin; G" represents the loss elastic modulus of the thermoplastic resin; and (η|ε=2 - η|ε=1) represents the slope of the elongation viscosity of the thermoplastic resin.
(FR) L'invention concerne un film optique qui est formé dans une résine thermoplastique, la résine thermoplastique contenant un copolymère séquencé hydrogéné (G) qui contient au moins deux blocs polymères (D) par molécule, lesdits blocs polymères (D) étant principalement constitués d'une unité hydrure de composé contenant un groupe hydrocarbure cyclique (I) et d'un ou plusieurs blocs polymères (E) par molécule, lesdits blocs polymères (E) étant principalement constitués d'une unité hydrure de composé hydrocarbure à chaîne (II) ou d'une combinaison de l'unité (I) et de l'unité (II); et la résine thermoplastique satisfait à G"/G' > 0,95 ou (η|ε =2 - η|ε =1) > -1,0 × 104 Pa·s. Dans la formule, G' représente le module d'élasticité de stockage de la résine thermoplastique; G" représente le module élastique et de perte de la résine thermoplastique; et (η|ε =2 - η|ε =1) représente la pente de la viscosité à l'allongement de la résine thermoplastique.
