    摘要： An aqueous polymer dispersion whose polymer, present in disperse distribution, is composed in free-radically polymerized form of from 20 to 65% by weight of at least one vinylaromatic monomer (monomers A), from 30 to 75% by weight of at least one monomer having two conjugated, ethylenically unsaturated double bonds (monomers B), and from 0.5 to 10% by weight of at least one other monomer, C, selected from the group consisting of &agr;,&bgr;-monoethyienically unsaturated mono- and dicarboxylic acids and amide or ester derivatives thereof and whose alkali metal ion content GA, based on the mass of the dispersed polymer, is ≧0.5% by weight, the pH of the aqueous dispersion medium being adjusted to a value below 6.

    摘要： A molding based on finely divided organic and/or inorganic materials containing, as binder, the solid component of an aqueous polymer dispersion which is obtainable by polymerizing unsaturated monomers which can be polymerized by means of free radicals in the aqueous phase in the presence of a monosaccharide, oligosaccharide, polysaccharide, oxidatively, hydrolytically and/or enzymatically degraded polysaccharide, chemically modified monosaccharide, oligosaccharide or polysaccharide, or a mixture of the said compounds, by the process of free-radical aqueous emulsion polymerization.
