The present invention relates to a process for producing polymer-containing coatings for surfaces by in situ precipitation of calcium carbonate. The invention is additionally directed to the polymer-containing coating as such and to surfaces to which such polymer-containing coatings have been applied. The polymer-containing coatings preferably have antibacterial action.

Process for producing polymer-containing coatings

The present invention relates to a process for the preparation of nanoparticulate zinc oxide in the form of aqueous suspensions or in the form of pulverulent solid. Furthermore, the invention relates to the use of zinc oxide particles and suspensions prepared in this way in cosmetic sunscreen preparations, as stabilizer in plastics, in paints, in coatings and as antimicrobial active ingredient.

Process for the preparation of nanoparticulate zinc oxide

A process for removing residual monomers from water-absorbing polymer particles, wherein the water-absorbing polymer particles are thermally aftertreated in a mixer with rotating mixing tools at a temperature of at least 60&#xb0; C. in the presence of water vapor.
