摘要: The present invention is directed to a thickener composition for thickening aqueous systems which contains mixture of a) water-soluble or water-dispersible containing urethane groups, b) non-ionic emulsifier and c) compound corresponding the formula (see I) wherein R1 R3 may be same different represent hydrocarbon radicals R2 R4 hydrogen radicals, Q represents alkylene oxide units obtained by alkoxylation alcohols with oxides having 2 4 carbon atoms, n number from 0 120. also relates use this as systems.
