ABSTRACT:
Improved polyetherimide compositions and processes for their production are described. Various polyetherimide derivatives including water-soluble and tri-functionalisocyanate cross-linked resins are described. They permit production of water-based enamels and coatable particulates which may be employed in, for example, formulation of insulated electrical conductors.
