| description | To provide a resin composition which gives a molding that suppresses occurrence of spitting during melt-molding, has sufficient heat and light resistances and is less likely to be formed into micro-plastic after disposal, and sufficiently improves each of the above characteristics compared to those using an ethylene-vinyl alcohol copolymer (EVOH).SOLUTION: A resin composition contains an EVOH (A), aluminum ions (B) and an antioxidant (G), in which at least a part of the EVOH (A) has at least one of a carboxylic acid unit (I) and a lactone ring unit (II) positioned on the polymer terminal, the total content (i+ii) of the carboxylic acid unit (I) and the lactone ring unit (II) per 1 g of the EVOH (A) is 14 μmol/g or more and 78 μmol/g or less, and a content (b) of the aluminum ions (B) per 1 g of the EVOH (A) is 0.002 μmol/g or more and 0.17 μmol/g or less.SELECTED DRAWING: None
【課題】溶融成形時のブツの発生が抑制され、十分な耐熱耐光性を有し且つ廃棄後にマイクロプラスチック化し難い成形体が得られる樹脂組成物であり、同じエチレン－ビニルアルコール共重合体（ＥＶＯＨ）を用いたものと比較して上記の各特性が十分に改善されている樹脂組成物等を提供する。【解決手段】ＥＶＯＨ（Ａ）、アルミニウムイオン（Ｂ）及び酸化防止剤（Ｇ）を含有し、ＥＶＯＨ（Ａ）の少なくとも一部が、重合体末端に位置するカルボン酸類単位（Ｉ）及びラクトン環単位（ＩＩ）の少なくとも一方を有し、ＥＶＯＨ（Ａ）１ｇあたりのカルボン酸類単位（Ｉ）及びラクトン環単位（ＩＩ）の合計含有量（ｉ＋ｉｉ）が１４μｍｏｌ／ｇ以上７８μｍｏｌ／ｇ以下であり、ＥＶＯＨ（Ａ）１ｇあたりのアルミニウムイオン（Ｂ）の含有量（ｂ）が０．００２μｍｏｌ／ｇ以上０．１７μｍｏｌ／ｇ以下である、樹脂組成物。【選択図】なし |
