    Abstract: An improved method of grinding polyaryletherketones, providing very good yields and the production of powders of polyaryletherketones with an average diameter below 100 μm having a narrow size distribution with few fine particles (Dv10>15 μm). Method of grinding polyaryletherketones of apparent density below 0.9 carried out in a temperature range between 0° C. and the glass transition temperature of the polymer measured by DSC, in order to obtain powders having a particle size distribution (diameters by volume) of d10>15 μm, 50
