Silane-modified additives and silane-modified polymer compounds
The invention relates to silane modified additives obtained by condensation of one or a plurality of silanes of the general formula (RO)3-nR1nSi(R2X)(1), wherein R is an optionally substituted alkyle, aryle or alkoxyalkyl radical with 1 to 10 carbon atoms or hydrogen, R1 an optionally substituted hydrocarbon radical with 1 to 12 carbon atoms or hydrogen, R2 an 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 R2 via a covalent bond and stands for an amino radical NHR3, an epoxy radical CR4(O)CR5R6, an urethane radical NR3—C(═O)OR3, an urea radical NR3—C(═O)NR3R4, a phosphorous acid radical P(═O)(OH)2, an anhydride radical C(═O)O(O═)CR3 or a carbon acid radical, wherein R3 is hydrogen or an optionally substituted alkyle, aryle or amino alkyle radical with 1 to 10 carbon atoms, R4, R5, R6 hydrogen or an optionally substituted alkyle or aryle radical with 1 to 10 carbon atoms, wherein the respective radicals R1, R2, R3, R4, R5 and R6 each 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.
