ABSTRACT:
Disclosed is a solution including an aromatic bis (ether dicarboxylic acid) component, an organic diamine component and a solvent system including a water-soluble organic solvent component, which may be a dipolar aprotic solvent or a monoalkyl ether of ethylene glycol or of diethylene glycol, and optionally water. The solution may be coated on a substrate and polymerized to form high quality polyetherimide coatings.
