    摘要: Toner particles are prepared by a process comprising providing an extrusion apparatus; adding resin particles and additive particles to a supply means in the extrusion apparatus; adding the resin particles and the additive particles to a blending chamber in the extrusion apparatus, which blending chamber is maintained at a temperature of from about 50° C. to about 120° C.; blending the resin particles and the additive particles to form a mixture; extruding the resin particles to form extruded material; injecting liquid substances, which have a lower boiling point than the melt temperature of the resin particles, into the blending chamber during extrusion without the application of a vacuum to remove the liquid substances prior to extrusion; and grinding the extruded material to form toner particles.

    摘要: A process for the preparation of pigmented toner compositions comprising: a) forming at a first temperature, a first melt mixture comprised of a partially crosslinked thermoplastic resin, pigment, optionally a wax, and optional additives, wherein the partially crosslinked thermoplastic resin is comprised of a mixture of crosslinked resin macrogel particles, crosslinked resin microgel particles, and uncrosslinked resin; and b) melt mixing at a second temperature, the first melt mixture to form a second mixture, wherein the macrogel particles are partially converted into microgel particles, and wherein the second temperature is less than or equal to the first temperature.
