Abstract

Process for the production of aqueous polymer dispersions by reaction of one or more olefinically unsaturated compounds in aqueous medium in the presence of a complex compound which possesses the structural element Y—M—E, E standing for nitrogen, M for a transition metal of groups 7 to 10 of the periodic system of the elements and Y for oxygen, sulfur, nitrogen or phosphorus, and which possesses no hydrophilic groups in its ligand system.
