LIQUID CRYSTALLINE POLY(ESTER-AMIDES)

摘要

Disclosed herein are thermotropic liquid crystalline poly(ester-amides) containing repeat units derived from aliphatic diamines and other monomers, such as aromatic diols, aromatic dicarboxylic acids, aromatic hydroxycarboxylic acids, and optionally aliphatic diols. The polymers are particularly useful as films and in multilayer structures as barrier layers because of their relatively low permeability to various compounds.
