Abstract: A toner process comprising (a) providing at least one amphiphilic block copolymer prepared by surfactant-free emulsion polymerization comprising: dissolving a hydrophilic monomer in water; adding a hydrophobic monomer; adding a feed initiator to produce a colloidal dispersion of amphiphilic block copolymer; and optionally, discharging the amphiphilic block copolymer; (b) contacting one or more of a latex polymer, a wax; and a colorant with the colloidal dispersion of amphiphilic block copolymer to form a blend; or contacting the discharged amphiphilic block copolymer with one or more of a latex polymer, a wax dispersion, and a colorant dispersion, and forming a further dispersion; (c) heating the blend or further dispersion at a temperature below the glass transition temperature of the latex polymer to form aggregated toner particles; (d) adding a coalescing agent to the toner particles thereby coalescing the toner particles; and (e) recovering the toner particles.
