<p>Process for preparation of monomers of the formula wherein R is hydrogen or methyl; X and Y are independently selected from the group consisting of NO2, halogen, -CN and -CF3; and m and n can range from 0 to 3. Typical monomers embraced by the above formula can be prepared by Lewis Acid catalyzed esterification of methacrylic acid with a diazo derivative of an electron acceptor such as 9-diazo-2,4,7-trinitrofluorenone. These monomers can be used with other binders or polymerized by standard, free-radical techniques to polymers capable of forming self-supporting films which are useful in electrophotographic imaging members and methods.</p> |
