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.
本发明涉及一种对
水性聚合物分散体的聚合物颗粒进行改性的工艺,在该工艺中,带正电或负电的聚合物颗粒带有
无机盐壳。
无机盐壳提高了胶乳的干燥能力和贮存稳定性,并改善了所得聚合物粉末的贮存稳定性。得到的聚合物粉末在最终应用中具有更好的粘度和更快的表皮形成时间,因此特别适用于建筑材料组合物。
