Abstract

A process for the repeatable production of shaped particles of various geometries from polymer dispersions, melts or solutions, wherein first particles are expelled by means of a rotating disk and are introduced while still liquid, in a radially outward direction, into a liquid precipitant or fixant film and the particles are thereby coagulated or fixed and also given an additional structure and are transported away from the point of introduction.
