摘要： Toner particles may be produced using a semisuspension polymerization process, which includes: (a) providing a mixture of a partially polymerized monomer or comonomers near the onset of the gel-effect; (b) forming a suspension of the partially polymerized monomer or comonomers; and (c) suspension polymerizing the partially polymerized monomer or comonomers while slowly adding a second monomer or comonomers in a starved feed manner. The process may be used to produce toner particles having varied particle properties, and having a morphology ranging from core-shell and inverted core-shell microcapsules to pseudo core-shell microcapsules and to polyblend composites having a low molecular weight phase dispersed in a high molecular weight matrix.

摘要： Submicron to micron sized conductive particles, on the order of 0.05 to 5 micron in average particle diameter, are produced using a semisuspension polymerization process in which the aqueous phase of the suspension contains an inorganic salt such as potassium iodide. The inorganic salt inhibits the formation of polymer particles that do not contain conductive filler so as to be non-conductive. The process also allows for conductive filler to be added at the start of the process. Powder coatings made from the submicron sized conductive particles have a high and uniform conductivity.
