Patent ID: 7723435

Claim:
A single-layered structure comprising (A) 50 to 97% by weight of a polyolefin, (B) 2 to 45% by weight of a polyamide resin comprising a diamine component and a dicarboxylic acid component, at least 70 mol % of the diamine component being a constitutional unit derived from m-xylylenediamine and at least 70 mol % of the dicarboxylic acid component being a constitutional unit derived from a C 4 -C 20 straight-chain α,ω-aliphatic dicarboxylic acid (X) and isophthalic acid (Y), in a molar ratio of X/Y of 3:7 to 10:0, and (C) 1 to 45% by weight of a modified polyolefin and/or styrene copolymer, the polyamide resin B being dispersed in sub-layers throughout the single-layered structure.
