manufacturing process, based on non aqueous dispersionstechniken,for the production of spherical polyester particles with narrow teilchengru00f6ssenverteilungen and controlled average teilchengru00f6ssen

摘要

The invention relates to a process for the production of spherical, polyester particles, wherein the particle size can be exactly adjusted in the range of 1 to 200 mu m and a particle size distribution with a span (=d90-d10/d50) ≤ 1.5, as well as the use of the produced particles for toner compositions in electrophotographic and direct printing systems and powder coatings.
