Abstract: Propenyl group free silicone-polyether copolymer (I) is claimed. Propenyl group free silicone-polyether copolymer of formula (I) is claimed. R : optionally saturated 1-20C-alkyl or 1-20C-haloalkyl; a1 : 0-2; a2 : 1-3; b : 0-2, where the sum of a1, a2 and b is 3; c : 0-22; d : 1-500; e : 0-10000; f, g : 0-1000; h, i, j : 0-500; n : 2 or 8; R 1> : OH, cyclic 1-1500C-oxyorganic residue (which is optionally saturated, further substituted and optionally interrupted by heteroatoms of O, S, Si or N), an oxyaromatic system containing residue or an unsaturated ether functional, in which there is no C-C double bond in a beta -position to an oxygen or C-C double bond are present only terminally; R 2>, R 3>, R 5>, R 6> : H, optionally mono or polyvalent hydrocarbon (which is optionally saturated and further substituted), where R 5>or R 6>is an univalent hydrocarbon and the hydrocarbon is cycloaliphatically bridged over the fragment Y 1>; Y 1> : absent, a methylene bridge with 1 or 2 methyl units, when Y 1>is absent, R 2>or R 3>is a 1-20C-residue; R 4> : 1-24C-alkyl, aromatic or cycloaliphatic residue (optionally containing alkyl); R 7>, R 8> : either H, alkyl, alkoxy, aryl or aralkyl; R 9>-R 1> 2> : either H, alkyl, alkenyl, alkoxy, aryl or aralkyl, where the hydrocarbon residue is cycloaliphatically or aromatically bridged over a fragment Z; Z : a divalent alkylene or alkenylene; R 1> 3> : either H (preferred) or W 1>; W 1> : organomodified silyl or siloxanyl residue of formula (-O-[Si(X) 2-O] k-[Si(X 1>) 2-O] l-[Si(X)(X 1>)-O] m-Si(X) 2-X 2>) (II); k-m : 0-200; X : cyclic, aliphatic or aromatic 1-20C-hydrocarbon (which is optionally saturated and optionally contains heteroatoms of O, N, P or S); X 1> : H, cyclic, aliphatic or aromatic 1-20C-hydrocarbon (which is optionally saturated and contains heteroatoms of O, N, P or S); and X 2> : X, X 1>or alkoxy group. Provided that: the sum of d-j is >= 3, when R 1>has only one monomer or oligomer; the fragments with the indices d, e, f, and/or h are freely permutable with one another, as are the fragments with the indices k-m, i.e. are exchangeable for one another within the polyether chain or the siloxane chain and may be present as desired in random distribution or in block sequence and hence are exchangeable for one another in the sequence within the polymer chain. Independent claims are included for: (1) a composition comprising (I) and further silicone surfactants, organic surfactants, solvents e.g. alkanes, halogenated alkanes, optionally substituted aromatics, esters, ethers, glycols, natural or synthetic oils or polyethers, amines, amides, acids, bases or their buffer system for adjusting the pH-value, flame retardants, catalysts, antioxidants, additives to control the rheological characteristics, e.g. thickeners, wetting agents or leveling agents, dispersing additives, solid inorganic or organic fillers, particles, binders, solid or liquid dyes, stabilizers, UV-absorbers, biocides and/or antistats; and (2) the preparation of (I), comprising either reacting gelling free alkoxysilyl functional organic polymer with a reactive silane, water and in the presence of a catalyst through selective complete or partial hydrolysis and condensation reaction, or reacting alkoxysilyl group functionalized polyether with a silane compound and/or a siloxane compound under hydrolytic conditions, an acid catalyst and/or metal complex catalyst, where the silane compound and/or a siloxane compound are reactively hydrolytically cleavable and condensable.
