    摘要: The present invention relates to ureaurethanes of the following formula (1) in which at least one of the R
    1 or R
    2 radicals is a mono- or polyunsaturated, branched or unbranched alkenyl or alkynyl radical having 12 to 24 carbon atoms, n is an integer ≥ 1, where the upper limit for n arises from the maximum number average molecular weight M
    n of the ureaurethanes of the general formula (I), which is 65 000 g/mol, and which is determined by means of gel permeation chromatography to DIN 55672-2 using a polymethyl methacrylate standard, R
    3 is a xylylene radical or a hydrogenated xylylene radical and R
    4 is a tolylene radical or various other radicals. The invention also relates to ureaurethane compositions comprising the ureaurethanes of the invention and to the preparation of both. The invention further relates to the use of the ureaurethanes or ureaurethane compositions as rheology control agent and anti-settling agent. The invention further provides liquid formulations from the group consisting of coating compositions, polymer formulations, pigment pastes, sealant formulations, cosmetics, ceramic formulations, drilling fluids, adhesive formulations, potting compounds, construction material formulations, lubricants, spackling compounds, printing inks and other inks, comprising the ureaurethanes and ureaurethane compositions.
