Abstract
(EN) As an ethylene-vinyl alcohol copolymer resin composition which is decreased in the viscosity with time during melt molding and has excellent long-run moldability, the present invention provides an ethylene-vinyl alcohol copolymer composition for melt molding, which contains an ethylene-vinyl alcohol copolymer (A), an alkali metal compound (B) and an iron compound (C), and which is configured such that the weight ratio of the content of the iron compound (C) in terms of metal to the content of the alkali metal compound (B) in terms of metal is from 10 to 100,000.
(FR) En tant que composition de résine de copolymère d'éthylène-alcool vinylique à viscosité réduite dans le temps pendant le moulage par fusion et présentant une excellente aptitude au moulage à long terme, la présente invention décrit une composition de copolymère d'éthylène-alcool vinylique pour moulage à chaud, qui contient un copolymère d'éthylène-alcool vinylique (A), un composé de métal alcalin (B) et un composé de fer (C), et qui est conçue de telle sorte que le rapport pondéral de la teneur du composé de fer (C) en termes de métal à la teneur du composé de métal alcalin (B) en termes de métal est de 10 à 100 000.
(JA) 溶融成形時に経時的に粘度低下し、ロングラン成形性が良好なエチレン-ビニルアルコール系共重合体樹脂組成物として、エチレン-ビニルアルコール系共重合体(A)、アルカリ金属化合物(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)の金属換算含有量に対する、上記アルカリ金属化合物(B)の金属換算含有量の重量比が、10~100000である溶融成形用エチレン-ビニルアルコール系共重合体組成物を提供する。
