Curable material comprising silylated polymers containing urethane groups, and use thereof in sealants, adhesives, binders and/or surface modifiers

A curable material comprising:

• urethane-group-containing reaction products, which is obtainable by reacting:
• a) at least one compound containing one or more isocyanate groups with;
• b) at least one compound bearing one or more alkoxysilyl groups and additionally bearing at least one hydroxyl group;
• c) optionally in the presence of one or more catalysts;
• d) optionally in the presence of further components reactive towards the reaction products;
• and
• e) optionally in the presence of further compounds which are not reactive towards the reaction products and reactants;
• wherein component (b) is one or more silyl polyethers 1 of the formula (2):
• where:
• a is an integer from 1 to 3;
• b is an integer from 0 to 2, and the sum of a and b is 3;
• c is an integer from 0 to 22;
• d is an integer from 2 to 500;
• e is an integer from 2 to 10,000;
• f is an integer from 0 to 1,000;
• g is an integer from 0 to 1,000;
• h, i, and j independently of one another are integers from 0 to 500;
• n is an integer between 2 and 8;
• R independently at each occurrence represents a radical selected from linear or branched, saturated, alkyl radicals having 1 to 20 carbon atoms or haloalkyl groups having 1 to 20 carbon atoms;
• R1 is a hydroxyl group or a saturated linear, branched or cyclic oxyorganic radical having 1 to 1500 carbon atoms, that is optionally further substituted, wherein the chain is optionally interrupted by a heteroatom or a radical comprising an oxyaromatic system;
• R2 and R3 are independently of one another, H, or a saturated or singly or multiply unsaturated monovalent or polyvalent hydrocarbon radical that is optionally further substituted, wherein R2 and R3 are optionally bridged via the fragment Y;
• R5 and R6 are independently of one another, H, or a saturated or singly or multiply unsaturated monovalent hydrocarbon radical that is optionally further substituted;
• Y is absent, or else is a methylene bridge having one or two methylene units;
• if Y is absent, then at least one of R2 or R3 independently of one another is a linear or branched hydrocarbon radical having 1 to 20 carbon atoms;
• R4 independently at each occurrence is a linear or branched alkyl radical of 1 to 24 carbon atoms or an aromatic or cycloaliphatic radical, which optionally further comprises alkyl groups;
• R7 and R8 are independently of one another either hydrogen or an alkyl, alkoxy, aryl or aralkyl group;
• and
• R9, R10, R11, and R12 are independently of one another either hydrogen or an alkyl, alkenyl, alkoxy, aryl or aralkyl group, wherein R10 and R11 are optionally bridged via the fragment Z, wherein Z is absent or is a divalent alkylene radical or alkenylene radical;
• with the proviso that the fragments having the indices d, e, f and/or h are present with statistical distribution or blockwise sequencing.
