Abstract

Process for preparing non-aqueous dispersions, wherein a liquid prepolymer is emulsified in a non-aqueous liquid, the droplet size of the emulsion is adjusted to 0.1 to 30 .mu.m and the droplet size distribution U.sub.90 is adjusted to less than 2 by means of a jet disperser, and the droplets are cured by a chemical reaction.
