Abstract: A nonlimiting example method for synthesizing a pigment-pendent polyamide (PP-polyamide) may comprise: functionalizing metal oxide particles bound to a pigment particle with a compound having an epoxy to produce a surface treated pigment having a pendent epoxy; and reacting the pendent epoxy with a polyamide to yield the PP-polyamide. Another nonlimiting example method for synthesizing a PP-polyamide may comprise: functionalizing metal oxide particles bound to a pigment particle with a silica particle having a carboxylic acid surface treatment to produce a surface treated pigment having a pendent carboxylic acid; converting the pendent carboxylic acid to a pendent acid chloride; and reacting the pendent acid chloride with a polyamide to yield the PP-polyamide. Said PP-polyamide may be useful in producing objects by methods that include melt extrusion, injection molding, compression molding, melt spinning, melt emulsification, spray drying, cryogenic milling, freeze drying polymer dispersions, and precipitation of polymer dispersions.

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.
