Abstract:
(EN) Provided is an ethylene/vinyl alcohol copolymer composition which has satisfactory ultraviolet absorption capacity without any known ultraviolet absorber, has excellent thermal stability, and is inhibited from taking a color. The ethylene/vinyl alcohol copolymer composition comprises an ethylene/vinyl alcohol copolymer (A), a styrene derivative (B), and an iron compound (C), wherein the iron compound (C) is contained in an amount of 0.01-5 weight ppm, in terms of metal amount, of the ethylene/vinyl alcohol copolymer composition.
(FR) L'invention concerne une composition de copolymère d'éthylène/alcool vinylique qui présente une capacité d'absorption des ultraviolets satisfaisante sans aucun absorbeur d'ultraviolets connu, présente une excellente stabilité thermique, et ne peut prendre de couleur. La composition de copolymère d'éthylène/alcool vinylique comprend un copolymère d'éthylène/alcool vinylique (A), un dérivé de styrène (B) et un composé de fer (C), le composé de fer (C) étant contenu en une quantité de 0,01 à 5 ppm en poids, en termes de quantité de métal, de la composition de copolymère d'éthylène/alcool vinylique.
(JA) 公知の紫外線吸収剤を配合しなくても良好な紫外線吸収能を有し、熱安定性に優れ、着色が抑制されたエチレン-ビニルアルコール系共重合体組成物として、エチレン-ビニルアルコール系共重合体(A)、スチレン誘導体(B)および鉄化合物(C)を含有するエチレン-ビニルアルコール系共重合体組成物であって、上記鉄化合物(C)の含有量がエチレン-ビニルアルコール系共重合体組成物の重量あたり、金属換算にて0.01~5ppmであるエチレン-ビニルアルコール系共重合体組成物を提供する。
