Abstract

PURPOSE: To prepare the titled fine particles suitable for the improvement of the slippery of a polyester, by carrying out the wet pulverization of particles having specific particle size and particle size distribution in ethylene glycol, thereby making the particle size and the particle size distribution finer and more uniform than the original particles.
CONSTITUTION: Inorganic compound fine powder (e.g. kaolin) or especially pref. disintegrable crosslinked polymer finer powder (e.g. copolymer of methyl methacrylate and divinylbenzene) having an average particles diameter of 2W10μ (the diameter corresponding to the weight fraction of 50%) and the particle size distribution sharpness index (γ) of ≤3 (the sharpness index is represented by the ratio of the diameter of 25% weight fraction to that of 75% weight fraction), is slurrified with ethylene glycol to a slurry concentration of 2W50wt/vol%, and subjected to the wet pulverization for 10minW5hr esp. with a mixing and grinding mill to obtain fine particles having an average particle size of 0.5W2μ and the γ value of ≤2.3.
