Abstract
Laminar articles having improved barrier properties to organic solvents and gases, fabricated directly from polyolefin and modified polyamide, are disclosed. The modified polyamide is a blend of 97-40 wt % polyamide and 3-60 wt % of compatabilizer which is a polyether ester amide block copolymer or a mixture of the block copolymer and alkylcarboxyl-substituted polyolefin.
