A multi-layer structure excellent in the barrier properties against alcohol gasoline, particularly hydrocarbon components, and also excellent in the interlayer adhesion, low-temperature impact resistance, heat resistance and chemical resistance is provided. The stractive is a multi-layer structure comprising two or more layers including at least a layer (a) comprising (A) nylon 11 and/or nylon 12 and a layer (b) comprising (B) a polyamide resin (nylon 9T) consisting of a dicarboxylic acid component and a-diamine component, with 60 to 100 mol % of the dicarboxylic acid component being a terephthalic acid and 60 to 100 mol % of the diamine component being a diamine component selected from 1,9-nonanediamine and 2-methyl-1,8-octanediamine, and preferably further including a layer (c) comprising (A) nylon 11 and/or nylon 12 or (C) nylon 6.
A multi-layer structure comprising two or more layers including at least a layer (a) comprising (A) nylon 11 and/or nylon 12, and a layer (b) comprising (B) a polyamide resin (nylon 9T) consisting of a dicarboxylic acid component and a diamine component, with 60 to 100 mol % of the dicarboxylic acid component being a terephthalic acid and 60 to 100 mol % of the diamine component being a diamine component selected from 1,9-nonanediamine and 2-methyl-1,8-octanediamine.
A multi-layer structure comprising three or more layers including at least a layer (a) comprising (A) nylon 11 and/or nylon 12, a layer (b) comprising (B) a polyamide resin (nylon 9T) consisting of a dicarboxylic acid component and a diamine component, with 60 to 100 mol % of the dicarboxylic acid component being a terephthalic acid and 60 to 100 mol % of the diamine component being a diamine component selected from 1,9-nonanediamine and 2-methyl-1,8-octanediamine, and a layer (c) comprising (A) nylon 11 and/or nylon 12 or (C) nylon 6.
