Abstract
A silica functionalized with a siloxane is of the general formula (I), [SiO][RSiO][RRSiO][RSiO][OR](I). The indices a, b, c, d, e each independently have integer values a from 0 to 100, b from 0 to 100, c from 0 to 50, d from 3 to 200, e from 0 to 50, with the proviso that the sum of a, b and c is at least 1 and for more than 50% of the siloxanes in the mixture the sum of a, b and c is ≥4.
