Abstract: The invention relates to a method for producing polymer powder compositions which are redispersible in water and which are based on polymerisates of one or more ethylenically unsaturated monomers. In a first step, an aqueous polymerisate dispersion is produced by means of a radically initiated polymerization of one or more ethylenically unsaturated monomers in an aqueous medium, said polymerisate dispersion being convened into the polymer powder composition which is redispersible in water by means of a diving process. The invention is characterized in that the polymerization and the drying process are each carried out in a continuous manner, and the polymerization and the diving process are carried out in separate interconnected modules.

Abstract: The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done in multiple steps such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.

Abstract: The invention describes powders for use in the production of spatial structures, i.e. molded bodies, using layer build-up methods, as well as methods for their efficient production. The powders have the special feature that they have good flow behavior, for one thing, and at the same time, have such a composition that the molded body that can be produced with the powder, using rapid prototyping, has significantly improved mechanical and/or thermal properties. According to a particularly advantageous embodiment, the powder has a first component that is present in the form of essentially spherical powder particles, which is formed by a matrix material, and at least one further component in the form of stiffening and/or reinforcing fibers, which are preferably embedded in the matrix material.
