Abstract

The present invention relates to a process for producing an aqueous polymer dispersion of polymerized ethylenically unsaturated monomers M having a polymer content of at least 55 wt. % and a polymodal particle size distribution of the polymer particles of the polymer dispersion. The invention also relates to aqueous polymer dispersions obtained from this process as well as aqueous liquid compositions comprising at least one aqueous polymer dispersion and the use of such aqueous liquid compositions as binder.
