New anhydride-functional organo (poly) siloxanes from average units of the general formula are described where R is identical or different, denotes a monovalent, optionally halogenated hydrocarbon radical having 1 to 18 carbon atoms per radical, A is a residue of the formula means, where R¹, R², R³ and R⁴ have the meaning given in claim 1, a 0 or 1, on average 0.003 to 1.0, b 0, 2 or 3, on average 0.05 to 2.5, and the sum of a + b is on average not greater than 3, with the proviso that at least one radical A is contained per molecule. |
