Claim:
A stable, hydrolysis-resistant aqueous emulsion comprising: silyl-functionalized polyethers, and optionally silyl-functionalized polyethersiloxanes, having in each case at least one nonterminal silyl function in the molecule; wherein the silyl-functionalized polyethers are compounds of the formula (1): where: a is an integer from 1 to 3; b is an integer from 0 to 2; the sum of a and b is 3; c is an integer from 0 to 22: d is an integer from 1 to 1000; e is an integer from 0 to 10,000; f is an integer from 0 to 1000; g is an integer from 0 to 1000; and h, i, and j are integers from 0 to 500; with the proviso that the fragments with the indices d to j are freely permutable with one another so as to be interchangeable with one another in the sequence within the polyether chain; and where: n is an integer between 2 and 8; R represents one or more identical or different radicals selected from linear or branched, saturated, singularly or multiply unsaturated alkyl radicals having 1 to 20 carbon atoms or haloalkyl groups having 1 to 20 carbon atoms; R 1 : is a radical, or a polyether radical selected from the group consisting of alkoxy, arylalkoxy, and alkylarylalkoxy radicals, in which the carbon chain is optionally interrupted by oxygen atoms; or is an optionally singularly or multiply fused aromatic aryloxy group; or is a silicon-containing compound or a siloxane radical or (poly)siloxane radical which is optionally alkyl- and/or aryl-group-substituted; R 2 and R 3 , identically or else independently of one another, are each: H; or a saturated or optionally singularly or multiply unsaturated, also further-substituted, optionally monovalent or polyvalent hydrocarbon radical, where R 2 and R 3 are optionally bridged cycloaliphatically via the fragment Y; Y: is not be present; or is a methylene bridge having 1 or 2 methylene units; where if Y is not present then R 2 or R 3 independently of one another is a linear or branched radical having 1 to 20 carbon atoms; R 4 : is a linear or branched alkyl radical of 1 to 24 carbon atoms; or is an aromatic or cycloaliphatic radical which may optionally in turn carry alkyl groups; R 5 and R 6 identically or else independently of one another, are each: H; or a saturated or optionally singular or multiply unsaturated, also further-substituted, monovalent hydrocarbon radical; R 7 and R 8 are, independently of one another, alternatively: hydrogen; or selected from the group consisting of alkyl, alkoxy, aryl, and aralkyl groups; and R 9 and R 12 are each, independently of one another, alternatively: hydrogen; or an alkyl, alkenyl, alkoxy, aryl, or aralkyl group; R 10 and R 11 are each, independently of one another, alternatively: hydrogen; or an alkyl, alkenyl, alkoxy, aryl, or aralkyl group, which is optionally bridged cycloaliphatically or aromatically via the fragment Z; and Z: is not be present; or is a divalent alkylene radical or an alkenylene radical.
