Summary: | The present invention provides an ethylene-vinyl alcohol copolymer resin composition which contains an ethylene-vinyl alcohol copolymer (X) and a metal compound and satisfies formula (1) as an ethylene-vinyl alcohol copolymer resin composition having excellent gas barrier properties under high humidity, particularly excellent oxygen barrier properties under high humidity. Delta A2 is equal to A2-A2, 0gt; (1) (A2 represents a second virie coefficient when static light scattering measurement is performed on the ethylene-vinyl alcohol copolymer resin composition using hexafluoroisopropanol as a solvent, and A2 and 0 represent the second virie coefficient of the ethylene-vinyl alcohol copolymer (X) in the ethylene-vinyl alcohol copolymer composition when the same measurement is performed. ).
作为高湿度下的阻气性、特别是高湿度下的氧气阻隔性优异的乙烯-乙烯醇系共聚物树脂组合物,本发明提供一种乙烯-乙烯醇系共聚物树脂组合物,其含有乙烯-乙烯醇系共聚物(X)和金属化合物,且满足下述式(1)。ΔA2=A2-A2,0>0···(1)(上述A2表示使用六氟异丙醇作为溶剂、并进行上述乙烯-乙烯醇系共聚物树脂组合物的静态光散射测定时的第二维里系数,A2,0表示相同测定时上述乙烯-乙烯醇系共聚物组合物中的乙烯-乙烯醇系共聚物(X)的第二维里系数。)。 |
