Verfahren zur Herstellung von wässrigen Polymerdispersionen

摘要

The invention relates to a process for producing protective colloid-stabilized aqueous polymer dispersions, whereby ethylenically unsaturated monomers are radically polymerized according to the emulsion polymerization method, characterized in that the polymerization is carried out in the presence of one or more protective colloids comprising a) 5 to 95 % of monomeric units containing sulfonic acid and sulfonate groups and b) 5 to 95 % of hydrophobic monomeric units from the group of water-insoluble and ethylenically unsaturated compounds, the given shares being expressed as a percentage of the total weight of the copolymerizate. The invention also relates to their use for making water-redispersible polymer powders.
