Abstract:
A protective-colloid-stabilized polymer composition in the form of its aqueous polymer dispersion or water-redispersible polymer powder, which consists essentially of at least one film-forming base polymer which is an addition polymer of one or more monomers selected from the group consisting of the vinyl esters of unbranched or branched carboxylic acids having from 1 to 12 carbon atoms, the esters of acrylic acid and methacrylic acid with unbranched or branched alcohols having from 1 to 12 carbon atoms, vinyl aromatics, vinyl halides, olefins and dienes, and a protective colloid, wherein the protective colloid is a sulfonated condensation product selected from the group consisting of (a) sulfonated polyesters of ethylenically unsaturated di- or polycarboxylic acids and saturated diol or polyols, and (b) sulfonated polyamides of ethylenically unsaturated di- or polycarboxylic acids and saturated diamines or polyamines.
