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'-isopropylidene bisphenol with .alpha.,.alpha.'-bis(4-hydroxybenzamido)-1,3-xylene exhibits especially high barrier.
