The present invention provides aqueous polymer dispersions that can be converted to elastomers or resins after the water has been removed, methods for their preparation, and their use as sealants, adhesives, and paint materials. Objective. (A) Organosilicon compound, polyurethane, polyol, precursor compound of polyurethane, precursor compound of crosslinked epoxide, precursor compound of crosslinked polyepoxide, amine, polyamine, amidoamine, polyamidoamine, mercaptan, polymercaptan, carboxylic acid, poly An organic compound selected from the group consisting of a carboxylic acid, a carboxylic acid anhydride, a polycarboxylic acid anhydride, an acrylate and its precursor compound, and a polysulfide-forming polymer, and (B) a portion of the surface is silylated, An aqueous dispersion comprising silica particles that are partially water-soluble and (C) water, wherein the silica particles have an average particle size of 1 nm to 5000 nm.
