Abstract
Aqueous polymer dispersions containing polymers obtainable by free-radical polymerization of unsaturated monomers, and sugared starch, and the use thereof.
Claims22
A polymer powder obtained by drying an aqueous polymer dispersion, wherein said aqueous polymer dispersion is obtained by free-radical polymerization of one or more unsaturated monomers and contains at least one added starch-degradation product which is obtained by a process consisting of hydrolysis of a native starch in the aqueous phase, wherein the starch degradation product has a weight average molecular weight M.sub.w of from 2500 to 25000 and an aqueous solubility of at least 40% by weight at room temperature.
