  • Patent number: 10407385
    Abstract: The present invention relates to ureaurethanes of the following formula (I) in which at least one of the R1 or R2 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 Mn 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, R3 is a xylylene radical or a hydrogenated xylylene radical and R4 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 antisettling agent.
