Provided is a resin composition comprising 1-99% by weight of a modified ethylene-vinyl alcohol copolymer (C) having an ethylene content of 5-55 mol%, which contains a specific structural unit (I) in an amount of 0.3-40 mol% and can be obtained by reacting an ethylene-vinyl alcohol copolymer (A) with a monofunctional epoxy compound (B) having a molecular weight of not more than 500, and 1-99% by weight of a thermoplastic resin (T1) other than (C). Moreover, a multilayer structure in which the resin composition and a thermoplastic resin (T2) are laminated is also provided. Thus, a resin composition superior in barrier properties, transparency, stretchability, flexibility, flexing resistance and interlayer adhesiveness and various kinds of molded articles made thereof are provided.
本发明提供了一种树脂组合物,该树脂组合物包含 1-99% (重量)的改性乙烯-乙烯醇共聚物 (C),其乙烯含量为 5-55 摩尔%,其中特定结构单元 (I) 的含量为 0.3-40 摩尔%,可通过乙烯-乙烯醇共聚物 (A) 与分子量不超过 500 的单官能环氧化合物 (B) 反应而获得;以及 1-99% (重量)的热塑性树脂 (T1) ,而非 (C)。此外,还提供了树脂组合物与热塑性树脂(T2)层压的多层结构。因此,本发明提供了一种在阻隔性、透明度、拉伸性、柔韧性、抗弯曲性和层间粘合性方面都很出色的树脂组合物,以及由其制成的各种模塑制品。
