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.

Aqueous polymer dispersion with polymer particles exhibiting polyol

A paper coating composition consisting essentially of an aqueous plastic dispersion which is based on .alpha.-methyleneglutaronitrile, a C.sub.8 - to C.sub.12 - monovinylaromatic compound, a plasticizing component selected from the group consisting of C.sub.4 - to C.sub.6 acyclic, conjugated diolefines and C.sub.4 - to C.sub.8 - alkyl (meth)acrylates, and a C.sub.3 - to C.sub.6 .alpha., .beta.-monoethylenically unsaturated carboxylic acid as binder, and conventional auxiliaries.
