Abstract (en)
[origin: WO2021190766A1] The invention relates to PFPA-containing siloxane oligomer mixtures, selected from compounds of the average formula [SiO4/2] a [RSiO3/2] b [R1SiO3/2] b' [R2SiO2/2] c [R1 2SiO2/2]c' [RR1SiO2/2]c'' [R3SiO1/2] d [R2R1SiO1/2] d' [RR1 2SiO1/2] d'' [R1 3SiO1/2] d''', wherein the indices a, b, b`, c, c`, c``, d, d`, d`` and d``` indicate the average content of the respective siloxane moiety in the mixture and independently of each other represent a number in the range of 0 to 300, with the proviso that the sum of all indices is in the range of 3 to 3500 and on average at least 2 radicals R are present; and the radicals R1 are independently of each other selected from the group consisting of (i) hydrogen, (ii) halogen, (iii) C1-C20 hydrocarbon radical, (iv) hydroxy radical and (v) C1-C20 hydrocarbon radical; and the radicals R are identical and represent a radical of the formula (I), wherein the radical X is selected from i) -O- or (ii) -NH-; and wherein the index n (i) for X = -O- takes a value in the range of 0 to 10, and (ii) for X -NH- takes a value in the range of 1 to 10.
