ABSTRACT:
An article of composition which has a barrier layer of an amorphous nylon copolymer. The copolymer is polymerized from (A) a lactam or aminoalkanoic acid, such as caprolactam, (B) an aralkylene or cycloalkylene diamine, such as m-xylylenediamine, and (C) one or more aromatic diacids, such as isophthalic acid and terephthalic acid. The copolymer barrier layer exhibits excellent oxygen barrier resistance when exposed to moisture.
