silane modified additives, process for preparing silane modified additives, process for preparing silane modified polymer compositions and use of silane modified additives The present invention relates to silane modified additives obtainable by condensation of one or more silanes of the general formula (ro) 3- nr1nsi (r2x) (1), wherein r is an alkyl, aryl or alkoxyalkyl radical having 1 to 10 carbon atoms or hydrogen, r1 is a hydrocarbon radical of 1 to 12 carbon atoms. optionally substituted carbon or hydrogen, r2 is an alkylene radical of 1 to 20 optionally substituted carbon atoms in which methylene units which are not adjacent to each other may be substituted by groups -or, eg is attached to r2 through a covalent bond and means an amino radical nhr3, a radical an epoxy radical cr4 (o) cr5r6, a urethane radical nr3-c (= o) or3, a radical ure ia nr3-c (= o) nr3r4, a phosphoric acid radical p (= o) (oh) 2, an anhydride radical c (= o) o (o =) cr3 or a carboxylic acid radical, where r3 means hydrogen or an optionally substituted alkyl, aryl or aminoalkyl radical of 1 to 10 carbon atoms, r4, r5, r6 means hydrogen or an optionally substituted alkyl or aryl radical of 1 to 10 carbon atoms, with the respective radicals r1, r2 , r3, r4, r5 and r6, in each case, obtain their values independently of each other, and adopts the value 0.1, 2 or 3 in an aqueous solvent by mixing with one or more water soluble polymers, the content of which of water-soluble polymers is greater than 15% by weight relative to the dry mass of the silane-modified additive, and eventually drying of the aqueous mixture thus obtained.
