| 1. A process for preparing an aqueous polymer dispersion, comprising:
polymerizing at least one olefinically unsaturated compound in an aqueous medium in the presence of at least one dispersant;
wherein;
the polymerization is carried out in the presence of a solid polymerization catalyst; and
the aqueous medium contains an added organic solvent in an amount equal to or less than 1% by weight.
