Beschreibung
Zusammenfassung:	The present invention relates to a method for the manufacture of low viscosity aqueous polymer dispersions with a polymer content of more than 50 vol. % and a polymodal distribution of polymer particle sizes by radical, aqueous emulsion polymerization of ethylenically unsaturated monomers, comprising at least one monomer (A) selected from monomers having a neutral functional group, which can be converted, according to Ph-value of reaction mixture, into a charged functional group and C1-C2 alkyl esters of monoethylenely unsaturated monocarboxylic or dicarboxylic acids. The invention also relates to polymer dispersions obtained according to this method.
