Title (EN) ETHYLENE-VINYL ALCOHOL COPOLYMER COMPOSITION, PELLET, AND MULTILAYER STRUCTURE
(FR) COMPOSITION DE COPOLYMÈRE ÉTHYLÈNE-ALCOOL VINYLIQUE, GRANULE ET STRUCTURE MULTICOUCHE
(JA) エチレン－ビニルアルコール系共重合体組成物、ペレットおよび多層構造体
Abstract:
(EN) Provided are: an ethylene-vinyl alcohol copolymer composition which suppresses coloration after heating; and a multilayer structure. The ethylene-vinyl alcohol copolymer composition contains: (A) an ethylene-vinyl alcohol copolymer; (B) a quinone compound; and (C) an iron compound, wherein the content of (C) the iron compound is 0.01-20 ppm, in terms of metal, per the weight of the ethylene-vinyl alcohol copolymer composition.
(FR) L'invention concerne : une composition de copolymère éthylène-alcool vinylique qui supprime la coloration après chauffage ; et une structure multicouche. La composition de copolymère éthylène-alcool vinylique contient : (A) un copolymère éthylène-alcool vinylique ; (B) un composé quinone ; et (C) un composé du fer, la teneur en composé du fer (C) étant de 0,01 à 20 ppm, en termes de métal, par rapport au poids de la composition de copolymère éthylène-alcool vinylique.
(JA) 加熱後の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および多層構造体として、エチレン－ビニルアルコール系共重合体（Ａ）、キノン化合物（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０．０１～２０ｐｐｍであるエチレン－ビニルアルコール系共重合体樹脂組成物を提供する。
