Composition useful e.g. as adhesive, comprises olefinically functionalized siloxane oligomers exhibiting less olefinic group at silicon atom, fatty acid, and silyloxy crosslinked structural elements derived from alkoxysilanes
Composition comprises olefinically functionalized siloxane oligomer (I), which exhibit (a) not 1 olefinic group at silicon atom, (b) at least one fatty acid (II), and (c) silyloxy (Si-O)-crosslinked structural elements, which form chain-like-, cyclic-, crosslinked- or optionally spatially crosslinked structures, and are derived from alkoxysilanes. Composition comprises olefinically functionalized siloxane oligomer of formula ((R1O)[(R1O) 1 - x(R2) xSi(A)O] a[Si(Y1) 2O] c[Si(B1)(R4) y(OR3) 1 - yO] bR3) (I), which exhibit (a) not 1 olefinic group at silicon atom, (b) at least one fatty acid of formula (R5-COOH) (II), and (c) silyloxy (Si-O)-crosslinked structural elements, which form chain-like-, cyclic-, crosslinked- or optionally spatially crosslinked structures, and are derived from alkoxysilanes. A : olefinic group; B1 : saturated hydrocarbyl, where the ratio of A to B is 1:0-1:8; Y1 : OR3 or O 1 / 2(in crosslinked or optionally spatially crosslinked structures) or OR3; R1 : 1-4C alkyl (optionally branched and/or cyclic), optionally H, and/or -CO-R5; R3 : 1-4C alkyl (optionally branched and/or cyclic); R2, R4 : 1-15C alkyl (optionally branched or cyclic); R5 : optionally substituted 3-45C hydrocarbon; either a : = 1; and b, c : = 0; or a+b+c : = 2; and x, y : 0 or 1. An independent claim is also included for preparing the above composition, comprising reacting olefinically functionalized alkoxysilane compound of formula (A-Si(R2) x(OR11) 3 - x) (III), optionally alkoxysilane compound of formula (B1-Si(R4) y(OR13) 3 - y) (IV) and optionally tetraalkoxysilane compound of formula (Si(OR13) 4) (V) with a defined amount of water, in presence of fatty acid compound of formula (II), and/or olefinically functionalized carboxy silane compound of formula (A-Si(R2) x(OR14) 3 - x) (VI), and optionally in presence of a solvent, preferably alcohol, to obtain siloxane oligomers. R11, R13 : 1-4C alkyl (optionally branched and/or cyclic); and R14 : -CO-R5.
