Abstract

A method for producing spherical, jelled particles in which jelling liquid polymer pure or in solution by mechanical means is dispersed into spherically shaped particles with a narrow particle size distribution, after which the received particles after transport through gas, preferably air, are transferred into a solvent, in which the polymer is essentially soluble, at which the solvent has a temperature beneath the jelling point of the polymer. The produced jelled particles may finally be separated from the solvent.
