MANUFACTURING METHODS, BASED ON NON AQUEOUS DISPERSION TECHNIQUES, TO PRODUCE SPHERICAL POLYESTER PARTICLES WITH NARROW PARTICLE SIZE DISTRIBUTIONS AND TAILORABLE MEAN PARTICLE SIZES

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 µm and a particle size distribution with a $$ \text{span (=d90-d10/d50) ≤ 1.5}$$, as well as the use of the produced particles for toner compositions in electrophotographic and direct printing systems and powder coatings.
