ABSTRACT:
Novel fumaronitriles and dicyanophenanthrenes, for example, bis(4-fluorophenyl)fumaronitrile and 3,6-difluoro-9,10-dicyanophenanthrene which can be produced from the fumaronitrile, produce useful homopolymers and copolymers for high temperature applications; the homopolgymers and copolymers derived from the dicyanophenanthrenes can be converted to colored phthalocyanine group-containing polymers which are soluble in organic solvents and can be cast as films which may form the charge generating layer of an electrophotography device.
