摘要：
A process for the preparation of polymer powders from polymer dispersions by feeding a polymer dispersion continuously into an atomization apparatus and separately therefrom but at the same time also introducing a liquid agent, the dispersion and the liquid agent being completely mixed within at the most one second and the mixture being immediately thereafter dried with evaporation of the volatile constituents to form a powder composed of particles having an average diameter of from 0.05 to 1 mm, and the polymer powders prepared by this process.
