Claim Text:
1. A composition comprising an olefinically functionalized siloxane oligomer having not more than one olefinic radical on a silicon atom, wherein: the olefinically functionalized siloxane oligomer comprises Si-O-crosslinked structural elements that form a catenary, cyclic, crosslinked or optionally three-dimensionally crosslinked structure corresponding to a formula I, the structural elements are derived from one or more alkoxysilanes, A corresponds to an olefinic radical and is a linear, branched or cyclic alkenyl- or cycloalkenyl-alkylene-functional group having in each case 2 to 16 C atoms, B corresponds to a saturated hydrocarbon radical and is a linear, branched or cyclic alkyl radical having 1 to 16 C atoms, Y corresponds to OR R R R R a, b, c, x and y independently correspond to integers with 1≦a, 0≦b, 0≦c, and (a+b+c)≧2, z and x is 0 or 1, y and w is 0 or 1, a total chloride content in the composition is less than or equal to 250 mg/kg and the structural elements [R wherein the olefinically functionalized siloxane oligomer is present at greater than or equal to 30% (area %, GPC) in relation to the overall composition with a molecular weight (Mw) of 500 to 700 g/mol in the composition.
