摘要： The invention relates to a process for modifying polymer particles of an aqueous polymer dispersion in which positively or negatively charged polymer particles are provided with an inorganic salt shell. The inorganic shell leads to an improved drying ability and storage stability of the latex and improves the storage stability of the resulting polymer powder. The obtained polymer powder exhibits an improved viscosity and faster skin-forming time in the final application and is therefore particularly useful in a building material composition.

摘要： The invention relates to a process for preparing core-shell particles having a polymer core and a continuous silica shell. The in situ formed core-shell architecture suppresses film formation of the polymer and simplifies the subsequent drying process. The finally obtained free flowing polymer powder exhibits improved redispersibility and storage stability and imparts building material compositions improved viscosity and faster skin-forming time.
