Hydroxyl functionalized polyetheramines as barrier packaging for oxygen-sensitive materials |
摘要 |
Polyetheramines having improved barrier to oxygen are thermoplastic polymers having aromatic ether/amine repeating units in their backbones and pendant hydroxyl moieties. Such polyetheramines are prepared by reacting diglycidyl ethers of dihydric aromatic compounds such as the diglycidyl ether of bisphenol-A, hydroquinone, or resorcinol with amines having no more than two amine hydrogens per molecule, such as piperazine or ethanolamine.
