Abstract
A process for preparing aqueous polymer dispersions by means of a polymerization, conducted in an aqueous system, of at least one free-radically polymerisable ethylenically unsaturated monomer in the presence of a polymerisation initiator, wherein the pH of the aqueous dispersion is adjusted during the preparation process by adding at least two different, basic reagents, at least one of said basic reagents being added in a plurality of stages.
