Abstract
The present invention relates to a process for producing an aqueous polymer dispersion of polymerized ethylenically unsaturated monomers, where the process has a first polymerization step as an aqueous radical emulsion polymerization of a first monomer composition M.a and a subsequent further polymerization step as an aqueous radical emulsion polymerization of a second monomer composition M.b, where the monomers M comprise at least one monomer M0 which is selected from compounds of formula 1, wherein X is Cl, Br or OS(O)R, Y is H, Cl, Br, OS(O)R, C-C-alkyl, or C(═O)OR, Ris H or C-C-alkyl, Ris H or C-C-alkyl, Ris C-C-alkyl, Ris C-C-alkyl, Ris C-C-alkyl. The invention also relates to an aqueous polymer dispersion obtainable by such a process as well as the use of such dispersions.
