Summary:The present invention relates to a process of free-radically initiated aqueous emulsion polymerization for preparing an aqueous polymer dispersion, where compounds having at least one ethylenically unsaturated group (monomers) are emulsified in an aqueous medium by means of dispersants and are polymerized by means of a free-radical polymerization initiator in the presence of a N-oxyl radical (a compound having at least one A process of free-radically initiated aqueous emulsion polymerization, in which polymerization is conducted in the presence of a stable N-oxyl radical and the diameter of the monomer droplets in disperse distribution in the aqueous medium is 500 nm.
