ABSTRACT:
Disclosed herein are novel poly(imide-ethers) containing ortho substitution in the main chain of the polymer. These polymers are made from novel aromatic bis-carboxylic anhydrides which contain two ether groups attached to an aromatic ring in ortho positions to each other. The polymers are particularly useful for films, fibers and encapsulation, as well as thermoplastics.
