The invention relates to organosilane-modified polysiloxanes of the following formula: (see formula) where x - 0 to 200, y = 5 to 100, z = 0 to 50 and p = 1 to 25; R1, R2, R3, R4 and R5 independently of one another are saturated or unsaturated, straight-chain or branched alkyl radicals having 1 to 4 carbon atoms and/or aryl radicals having 6 to 9 carbon atoms; R6 is a straight-chain or branched alkyl radical having 6 to 22 carbon atoms; R7 is a radical -(CH2)s-M-Z, where s is 2 to 20, M is an aliphatic group containing at least one -O-CO- or -CO- O- group and optionally ether groups, and Z is hydrogen, -CO-CH3 or a straight-chain or branched alkyl radical having 1 to 4 carbon atoms; R8 is a radical -(CH2)n-Si(R11)v(R12)3-v, where v is 0, 1 or 2, n is 2 to 16, R11 is a straight-chain or branched alkyl radical having 1 to 4 carbon atoms, and R12 is a radical selected from the group OR13, O-CO-R13, halogen or haloalkyl having 1 to 6 carbon atoms, in which R13 is an aromatic radical or a straight-chain, branched or cyclic alkyl radical having 1 to 6 carbon atoms and optionally containing ether and/or thioether groups; and R9 and R10 independently of one another possess the definition of R1, R2, R3, R4, R5, R6, R7 or R8. The -28- invention additionally relates to the use of the organo-modified polysiloxanes for surface coating, and to their preparation. |
