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. 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.
本发明涉及下式(I)的脲基聚氨酯
其中 R1 或 R2 自由基中至少有一个是具有 12 至 24 个碳原子的单不饱和或多不饱和、支链或不支链烯基或炔基,n 为整数≥1,其中 n 的上限来自通式(I)脲烷的最大数均分子量 Mn、R3 是二甲苯基或氢化二甲苯基,R4 是甲苯基或其他各种基。本发明还涉及由本发明的脲基聚氨酯组成的脲基聚氨酯组合物及其制备方法。本发明还涉及脲聚氨酯或脲聚氨酯组合物作为流变控制剂和防沉降剂的用途。本发明进一步提供了由脲基聚氨酯和脲基聚氨酯组合物组成的液体配方,这些液体配方包括涂料组合物、聚合物配方、颜料膏、密封剂配方、化妆品、陶瓷配方、钻井液、粘合剂配方、灌封化合物、建筑材料配方、润滑剂、抹灰化合物、印刷油墨和其他油墨。
