Polyethers having improved barrier to oxygen are normally solid, thermoplastic polyethers having backbone repeating units of m-phenylene, p-phenylene, carbonyldiphenylene and/or sulfonyldiphenyl and pendent hydroxyl moieties. Such polyethers are prepared by reacting diglycidyl ethers of dihydric aromatic compounds such as the diglycidyl ether of bisphenol A with resorcinol.
