Title (EN) RESIN COMPOSITION AND MOLDED ARTICLE
(FR) COMPOSITION DE RÉSINE ET ARTICLE MOULÉ
(JA) 樹脂組成物及び成形体
Abstract:
(EN) Provided are: a resin composition that has excellent appearance properties and long-run properties when being melted and molded, and that can inhibit the occurrence of yellowing even after being repeatedly re-used; and a molded article obtained using such a composition. The resin composition according to the present invention contains EVOH as a major ingredient, and is characterized in that the resin composition contains a phosphorus compound and a metal salt, the phosphorus compound is a condensed phosphoric acid, a compound having two or more phosphonic acid groups, or a combination thereof, the contained amount of the phosphorus compound is not less than 0.1 ppm but less than 50 ppm, the contained amount of the metal salt is 5-500 ppm in terms of the elemental metal. The metal salt is preferably an alkali metal salt, an alkaline-earth metal salt, or a combination thereof. The molded article according to the present invention has a portion formed of the resin composition.
(FR) L'invention concerne une composition de résine qui présente propriétés d'aspect et des propriétés à long terme excellentes lorsqu'elle est fondue et moulée, et qui peut inhiber l'apparition de jaunissement même après avoir été réutilisée de manière répétée; et un article moulé obtenu en utilisant ladite composition. La composition de résine selon la présente invention contient de l'EVOH comme ingrédient principal et est caractérisée en ce que la composition de résine contient un composé de phosphore et un sel métallique, le composé de phosphore étant un acide phosphorique condensé, un composé ayant deux ou plusieurs groupes d'acide phosphonique ou une combinaison de ceux-ci, la quantité contenue du composé de phosphore n'étant pas inférieure à 0,1 ppm mais étant inférieure à 50 ppm, la quantité contenue du sel métallique allant de 5 à 500 ppm en termes de métal élémentaire. Le sel métallique est de préférence un sel de métal alcalin, un sel de métal alcalino-terreux, ou une combinaison de ceux-ci. L'article moulé selon la présente invention comprend une partie formée de la composition de résine.
(JA) 溶融成形における優れた外観特性やロングラン性を備え、特に再利用を繰り返した後においても黄変の発生を抑制することができる樹脂組成物、及びこのような組成物を用いて得られる成形体を提供する。本発明の樹脂組成物は、EVOHを主成分とする樹脂組成物であって、リン化合物及び金属塩を含有し、上記リン化合物が、縮合リン酸、2つ以上のホスホン酸基を有する化合物又はこれらの組み合わせであり、上記リン化合物の含有量が0.1ppm以上50ppm未満であり、上記金属塩の含有量が金属元素換算で5ppm以上500ppm以下であることを特徴とする。上記金属塩がアルカリ金属塩、アルカリ土類金属塩又はこれらの組み合わせであることが好ましい。本発明の成形体は、当該樹脂組成物から形成される部分を有する成形体である。
