Emulsions based on hydroxyl compounds bearing silyl groups

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;
• 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;
• 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;
• R2 and R3, 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 R2 and R3 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 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;
• or
• is 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;
• or
• a saturated or optionally singular or multiply unsaturated, also further-substituted, monovalent hydrocarbon radical;
• R7 and R8 are, independently of one another, alternatively:
• hydrogen;
• or
• selected from the group consisting of alkyl, alkoxy, aryl, and aralkyl groups;
• and
• R9 and R12 are each, independently of one another, alternatively:
• hydrogen;
• or
• an alkyl, alkenyl, alkoxy, aryl, or aralkyl group;
• R10 and R11 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.
