ABSTRACT:
A process and apparatus for the preparation of aqueous synthetic resin dispersions by using water to precipitate the synthetic resins from their solutions in water-miscible solvents. The solutions may contain pigments, extenders, and additives. The precipitated solids are separated off and dispersed uniformly in an aqueous medium. The precipitation of the synthetic resins is carried out in the presence of inert grinding bodies.
