Abstract

The invention relates to protective-colloid-stabilized polymer compositions in the form of their aqueous polymer dispersions or water-redispersible polymer powders, which comprise at least one film-forming base polymer and a protective colloid, wherein the protective colloid is a sulfonated condensation product made from unsaturated di- or polycarboxylic acids and from at least one compound selected from the class encompassing diols, polyols, diamines and polyamines.
