Polymer composition comprises olefinically functionalized siloxane oligomers of (I), at least one organic polymer, and an inorganic solid material, where the siloxane oligomers exhibit (a) not > 1 olefinic group at silicon atom, (b) at least one fatty acid (III), and (c) silyloxy (Si-O)-crosslinked structural elements, which form chain-like-, cyclic-, crosslinked- or optionally spatially crosslinked structures, and are derived from alkoxysilanes, and the siloxane oligomers are optionally chemically bonded to the inorganic solid material. Polymer composition comprises olefinically functionalized siloxane oligomers of formula ((R1O)[(R1O) 1 - x(R2) xSi(A)O] a[Si(Y1) 2O] c[Si(B1)(R4) y(OR3) 1 - yO] bR3) (I), at least one organic polymer, and an inorganic solid material, where the siloxane oligomers exhibit (a) not > 1 olefinic group at silicon atom, (b) at least one fatty acid of the formula (R5-COOH) (III), and (c) silyloxy (Si-O)-crosslinked structural elements, which form chain-like-, cyclic-, crosslinked- or optionally spatially crosslinked structures, and are derived from alkoxysilanes, and the siloxane oligomers are optionally chemically bonded to the inorganic solid material. A : olefinic group; B1 : saturated hydrocarbyl; Y1 : OR3 or O 1 / 2(in crosslinked or optionally spatially crosslinked structures) or OR3; R1, R3 : 1-4C alkyl (optionally branched and/or cyclic) or optionally H, and/or -CO-R5; R2, R4 : 1-15C alkyl (optionally branched or cyclic); either a : >= 1; and b, c : >= 0; or a+b+c : >= 2; x, y : 0 or 1; and R5 : 3-45C hydrocarbyl (optionally substituted). An independent claim is also included for: preparing the above composition, comprising reacting olefinically functionalized siloxane oligomers comprising at least one fatty acid of (III) with the organic polymer and the inorganic solid material in a compounding apparatus. |
