摘要
The invention relates to a method for reducing odor emissions of aqueous aromatic vinyl-1,3-diene-copolymer dispersions which have been stabilized with a protective colloid. The invention also relates to redispersion powders obtained by drying said dispersions. This is achieved by emulsion polymerization of a mixture containing at least one aromatic vinyl and at least one 1,3-diene in the presence of one or more protective colloids and by optionally drying the polymer dispersion obtained thereby. The invention is characterized in that 0.01 to 15.0 wt. % of one or more monomers selected from the group of branched or unbranched alkyl esters containing 1 to 8 carbon atoms in the alkyl radical of monounsaturated mono- or dicarboxylic acids are added at the end of the polymerization when the total content of the aqueous polymer dispersion containing free monomers ranges from 0 to =20 wt. %, whereby the given wt. % refers to the polymer content of the dispersion.
