Poly(hydroxy ether imides) as barrier packaging materials

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.

More Information
Summary: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 cm3-mil/100 in2-atm-day) and high heat resistance (i.e., Tg above 120 DEG C.). These polymers are suitable for use in the manufacture of packaging materials with high barrier to oxygen.
