ABSTRACT:
N-Vinyl carbazoles are prepared by reacting an N-unsubstituted carbazole with a dihaloethane in the presence of a phase transfer catalyst followed by reaction with an aqueous solution containing a highly basic agent. These N-vinyl carbazoles are useful, singly or in combination with other materials, as electrical capacitors and insulators, in thermal foam insulators, as components in copolymers and in image-recording systems, and as photoconductive materials in electrophotography.
