Polymers of benzanthracene as active matrix materials |
| abstract |
Vinyl polycyclic aromatics, particularly polycyclics having 3 or more nuclei and their polymers utilizable as active matrix material for xerographic purposes are obtained in high yield by initial conversion of the polycyclic reactant to the aldehyde in the presence of a haloalkyl ether as a formulating agent in the presence of a Friedl-Crafts type catalyst. The aldehyde intermediate is then converted to the vinyl monomer by using a Wittig-type reaction and, thereafter, polymerized, as desired, by the use of a cationic mechanism. |
