ABSTRACT:
Amorphous polymers which are soluble in organic solvents and can thus be cast as films have high glass transition temperatures which make them suitable for numerous high temperature applications; the polymers comprise ortho aromatic polyketones, polyphthalazines and polyisoquinolines, the polyphthalazines and polyisoquinolines being readily formed from the polyketones.
