摘要：
Disclosed is a method for producing an aqueous polymer dispersion, according to which unsaturated monomers are first polymerized by means of suitable catalysts, whereupon the obtained polymers that are swelled with all or some of the remaining unreacted monomers are added to surface-active substances and water in a last step in which the obtained polymers are not entirely separated from the remaining monomers.
