1. 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; andh, 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; andwhere:
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;R1:
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; oris an optionally singularly or multiply fused aromatic aryloxy group; oris a silicon-containing compound or a siloxane radical or (poly)siloxane radical which is optionally alkyl- and/or aryl-group-substituted;R2 and R3, identically or else independently of one another, are each:
H; ora saturated or optionally singularly or multiply unsaturated, also further-substituted, optionally monovalent or polyvalent hydrocarbon radical, where R2 and R3 are optionally bridged cycloaliphatically via the fragment Y;Y:
is not be present; oris a methylene bridge having 1 or 2 methylene units;where if Y is not present then R2 or R3 independently of one another is a linear or branched radical having 1 to 20 carbon atoms;R4:
is a linear or branched alkyl radical of 1 to 24 carbon atoms; oris an aromatic or cycloaliphatic radical which may optionally in turn carry alkyl groups;R5 and R6 identically or else independently of one another, are each:
H; ora saturated or optionally singular or multiply unsaturated, also further-substituted, monovalent hydrocarbon radical;R7 and R8 are, independently of one another, alternatively:
hydrogen; orselected from the group consisting of alkyl, alkoxy, aryl, and aralkyl groups; andR9 and R12 are each, independently of one another, alternatively:
hydrogen; oran alkyl, alkenyl, alkoxy, aryl, or aralkyl group;R10 and R11 are each, independently of one another, alternatively:
hydrogen; oran alkyl, alkenyl, alkoxy, aryl, or aralkyl group, which is optionally bridged cycloaliphatically or aromatically via the fragment Z; andZ:
is not be present; oris a divalent alkylene radical or an alkenylene radical. |
