Abstract
Hydroxy-functional poly(amide-ethers) are fabricated into articles such as rigid containers and flexible films exhibiting high barrier to oxygen transmission in both dry and moist environments. For example, a polymer prepared by reacting the diglycidyl ether of 4,4'-biphenol with N,N'-bis(m-hydroxyphenyl)-adipamide exhibits especially high barrier.
