摘要： Polyethers having improved barrier to oxygen are normally solid, thermoplastic polyethers having aromatic ether repeating units in their backbones and pendent hydroxyl moieties and pendent amido, N-substituted amido and/or hydroxyalkyl moieties. Such polyethers are prepared by reacting diglycidyl ethers of dihydric aromatic compounds such as the diglycidyl ether of bisphenol A with dihydric phenols having pendent amido, N-substituted amido and/or hydroxyalkyl moieties such as 2,2-bis(4-hydroxyphenyl)acetamide and 3,5-dihydroxybenzamide.

摘要： Poly(hydroxy ethers) are prepared by reacting a dihydric phenol with a diepoxide in the presence of a catalyst selected from the group consisting of bis(trihydrocarbylphosphoranylidene)ammonium salt, bis[tris(dihydrocarbylamino)phosphoranylidene]ammonium salt, and tetrakis[tris(dihydrocarbylamino)phosphoranylideneamino]phosphonium salt. The reaction between the dihydric phenol and the diepoxide is conducted in an ether or hydroxy ether solvent at a temperature sufficiently high to produce a poly(hydroxy ether). Polymers prepared by the new process are more highly branched than those produced by known methods.

摘要： Hydroxy-functionalized polyethers having imide groups in their backbones are prepared by contacting an imide-containing bisphenol with the diglycidyl ether of the same or another bisphenol under conditions sufficient to cause the nucleophilic phenolic hydroxyl moieties to react with epoxy groups. These poly(hydroxy ether imides) possess a combination of high barrier to oxygen transmission (i.e., oxygen transmission rates of less than 10.0 cm.sup.3 -mil/100 in.sup.2 -atm-day) and high heat resistance (i.e., T.sub.g above 120.degree. C.). These polymers are suitable for use in the manufacture of packaging materials with high barrier to oxygen.
