SUBSTANCE: invention relates to an injection molded multilayer article comprising a layer of a barrier polymer composition comprising (A) 20 to 60 wt.% polyamide polymer, comprising a diamine structural unit, 70 mol.% or more of which is derived from m-xylylenediamine, and a structural unit of dicarboxylic acid, 70 mol.% or more of which is derived from a dicarboxylic acid containing a linear aliphatic α, ω-dicarboxylic C₄-C₂₀-acid and an isophthalic acid in a molar ratio of 30:70 to 100: 0; (B) 80 to 40 wt.% of a modified polyolefin. Also disclosed is an obtained by injection molding, comprising (A) 10 to 60 wt.% of said polyamide polymer and (E) 40 to 90 wt.% of a mixed polyolefin, comprising (C) 40 to 90 wt.% polyolefin and ( B) 10 to 60 wt.% of a modified polyolefin, wherein at least part of polyamide polymer (A) is dispersed in a layered state in article, wherein said article is a single-layer container comprising a gas barrier layer.

EFFECT: said molded articles have good barrier characteristics.
