Abstract: Disclosed herein is a method for manufacturing a fluorinated structured organic film (FSOF) composition for a photoreceptor. The method includes combining a fluorinated diol, an electroactive segment and a solvent in a round bottom reactor. The reacted is heated, without mixing dissolve the fluorinated diol composition. The dissolved fluorinated diol composition is mixed to dissolve the electroactive segment while maintaining the reactor at a temperature of between 80 and 85° C. A catalyst and a leveling agent are added to the solution to initiate a pre-cure reaction. The pre-cure reaction proceeds for at least 2 hours at a temperature of between 80 and 85° C. The solution is cooled to room temperature and filtered.

Abstract: The present disclosure provides processes for producing toners by emulsion aggregation where the resulting toner particles have high pigment loadings and desired circularity. The methods include adding a metal, in embodiments a metal salt, at the beginning of coalescence, which surprisingly speeds the coalescence process and produces toner particles having a desired size and circularity for use in electrophotographic imaging systems.
