    摘要： The continuous process for manufacturing toners disclosed herein includes continuously feeding components of a toner composition into a feed section of a screw extruder at a controlled rate. The continuous process for manufacturing toners may include feeding the components of a toner composition into the feed section of a screw extruder without performing an external or secondary dispersion step. That is to say, the components of the toner composition may be fed directly into the extruder without using dispersions of individual components as used in batch processes. Rather, the toner components are added to the extruder in dry form, melt-mixed, and may be dispersed in aqueous form in the extruder. The process may produce micron-sized toner particles, thus no further size reduction may be necessary.

    摘要翻译： 本文公开的用于制造调色剂的连续方法包括以受控的速率将调色剂组合物的组分连续进料到螺杆挤出机的进料段中。 用于制造调色剂的连续方法可以包括将调色剂组合物的组分进料到螺杆挤出机的进料部分中，而不进行外部或二次分散步骤。 也就是说，调色剂组合物的组分可以直接进料到挤出机中而不使用分批方法中使用的各个组分的分散体。 相反，调色剂组分以干燥形式加入到挤出机中，熔融混合，并且可以以水性形式分散在挤出机中。 该方法可以产生微米级的调色剂颗粒，因此不需要进一步的尺寸减小。

    摘要： Porous polymer microspheres having a size of from about 3 to about 50 microns and a geometric standard deviation of about 1.25 or less are disclosed. The porous polymer microspheres are made by a method including the steps of preparing an emulsion comprised of polymer particles having an average particle size of less than about 3 microns and a diluent, subjecting the emulsion to an aggregating condition to form aggregated polymer particles, optionally coalescing the aggregated polymer particles, and removing the diluent to form the porous polymer microspheres.
