Silane-modified additives and silane-modified polymer compounds

Abstract

The invention relates to silane modified additives obtained by condensation of one or a plurality of silanes of the general formula (RO)RSi(RX)(1), wherein R is an optionally substituted alkyle, aryle or alkoxyalkyl radical with 1 to 10 carbon atoms or hydrogen, Ran optionally substituted hydrocarbon radical with 1 to 12 carbon atoms or hydrogen, Ran optionally substituted alkylene radical with 1 to 20 carbon atoms, wherein methylene units that are not adjacent to one another can be substituted by groups —O—, and X is bound to Rvia a covalent bond and stands for an amino radical NHR, an epoxy radical CR(O)CRR, an urethane radical NR—C(═O)OR, an urea radical NR—C(═O)NRR, a phosphorous acid radical P(═O)(OH), an anhydride radical C(═O)O(O═)CRor a carbon acid radical, wherein Ris hydrogen or an optionally substituted alkyle, aryle or amino alkyle radical with 1 to 10 carbon atoms, R, R, Rhydrogen or an optionally substituted alkyle or aryle radical with 1 to 10 carbon atoms, wherein the respective radicals R, R, R, R, Rand Reach obtain their values independently from each other, and n takes on the value 0, 1, 2, or 3, in an aqueous solvent by mixing with one or a plurality of water solvent polymers, wherein the content of water soluble polymers is ≧15 wt. %, based on the dry weight of the silane modified additives, and optionally drying of the thus obtained aqueous mixture.
