摘要： Use of one or more mixed hardenable hydroxyl group containing silylpolyether compound (Q) with at least one non-terminal silyl function as a component of composition as modifying- and/or coating-agent for surfaces, is claimed. Use of one or more mixed hardenable hydroxyl group containing silylpolyether compound (Q) of formula (I), (X 1>-Si(X) 2-O-(Si(X) 2-O) k-(Si(X)(X 2>)-O) l 3-(Si(X)(X 3>)-O) l 4-(Si(X 4>)(O-(Si(X) 2-O) k 1-(Si(X)(X 2>)-O) l 5-(Si(X)(X 3>)-O) l 6-Si(X) 2(X 1>))) o-Si(X) 2(X 1>)) (V), or a linear polyether-siloxane-polyether-triblock copolymer compound of formula (X 7>-O-Si(R1a) 2-(O-Si(R1a) 2) m-O-X 7>) (VI), with at least one non-terminal silyl function as a component of composition as modifying- and/or coating-agent for surfaces, is claimed. a : 1-3; b : 0-2, where the sum of a and b is 3, preferably less than 3; c : 0-22; c1 : 0-24; d : 1-1000, preferably 1-500; e : 0-10000; f, g : 0-1000; h, i, j : 0-500; n : 2-8; R : 1-20C-alkyl or 1-20C-haloalkyl; R 1> : optionally saturated, optionally branched residue, which is bonded over O, or a polyether residue of alkoxy-, arylalkoxy- or alkylarylalkoxy group, in which the carbon chain is optionally interrupted by O, an optionally mono- or polycyclic, annelated aromatic aryloxy group, a silicon containing compound or a siloxane residue optionally substituted by alkyl and/or aryl; R 2>, R 3>, R 5>, R 6> : H or optionally saturated, optionally substituted, optionally mono or polyvalent hydrocarbon, where R 5> or R 6> is similar to monovalent hydrocarbon, the cycloaliphatic hydrocarbon is optionally bridged over the fragment Y 1>, and R 2> are/or R 3> are a residue with 1-20 carbon atoms; Y 1> : CH 3 bridge with 1 or 2 methylene unit, or O; R 4> : 1-24C-alkyl or an aromatic or cycloaliphatic residue optionally containing alkyl group; R 7>, R 8> : H, alkyl-, alkoxy-, aryl- or aralkyl group, which becomes polyether ester copolymer under the ring opening polymerization of crosslinkable alkoxysilane group; R 9>-R 1> 2> : H, alkyl-, alkenyl-, alkoxy-, aryl- or aralkyl group, where the hydrocarbon residue is cycloaliphatically or aromatically bridged over Z; Z : a divalent alkylene and/or alkenylene residue; X : cyclic, aliphatic or aromatic, optionally saturated 1-20C-hydrocarbon optionally containing heteroatoms of O, N, P or S X 1> : X, X 2>, or X 3>; X 2> : an alkoxysilyl group containing OH functional polyoxyalkylene residue of formula (Va), which is optionally ester or carbonate modified; X 3> : a terminally etherified polyoxyalkylene residue of formula (Vb); R2a, R3a : 1-20C-hydrocarbon, which optionally contains halo, OH or glycidyloxypropyl, when Y 1> is O; R4a : 1-18C-alkyl optionally bonded to an aryl or cycloaliphatic residue; R7a, R8a : H, alkyl-, alkoxy-, aryl- or aralkyl group; R 1> 3> : 1-18C-alkyl or monofunctional carboxylic acid with terminal transesterified polyoxyalkylene residue of formula (Vc); R 1> 4> : optionally saturated, aliphatic or aromatic 1-30C-hydrocarbon, which contains OH groups; X 4> : X 1> or a fragment of formula (-O(-Si(X)-O) k 2-(Si(X)(X 2>)-O) l 7-(Si(X)(X 3>)-O) l 8-Si(X) 2-X 1>) (Vd); k, k1, k2 : 0-500; l3-l8 : 0-60; o : 0-10; R1a : optionally saturated 1-20C-alkyl; m : 0-5000; and X 7> : polyether fragment of formula (VIa). Provided that: fragments with the index d-j are freely permutable among one another, i.e. sequences are interchangeable against each other within the polyether chain; fragments with the index k, k1, l2, l3, l4, l5, l6, l7, l8 and o are freely permutable among one another, i.e. sequences are interchangeable against each other within the siloxane chain, and selectively statistically distributed or exist as a block; and X 1> is X 2>, when the sum of l3-l7 is 0 or X 1> is not equal to X 2>, when l3-l7 is at least 1. Independent claims are included for: (1) a composition for surface modification or coating comprising (I); (2) the surface modification of particles or films comprising applying the compositions containing (I) either under mixing, or in the presence of pure crosslinking catalyst, or from suitable organic and/or inorganic solvents on the particle surface or from emulsion, where the compounds react covalently or physically; and (3) the surface modification of particle surfaces comprising modifying the particle or a matrix dispersed particle by adding (Q) under mixing and optionally adding a suitable catalyst.
