ABSTRACT:
Production of polyenaminonitriles including those which can be cyclized to very stable poly(aminoquinolines) without the evolution of any small molecules and thus in a manner free of volatiles. The polyenaminonitriles are polymers which have desirable dielectric properties, and include those which can be cyclized to poly(aminoquinolines) without the evolution of volatiles to make defect-free films and composites of similar dielectric properties because of this characteristic.
