Abstract
The invention is directed to the preparation of aqueous polymer dispersions with polymer particles having polyol groups. The interfacial hydrophilia can be set in a desired manner. The dispersions contain substantially no dissolved macromolecular substances in the aqueous phase and are very stable. The dispersions are obtained through emulsion polymerization and subsequent modification.
