Abstract

The use of substituted diureas, polyureas, bisurethanes or polyurethanes of the formula R1X—CO—NR3R4 in which X is R2N or O and R1 to R4 are each independently hydrogen, alkyl radicals, alkenyl radicals, cycloalkyl radicals, aryl radicals or arylalkyl radicals, where at least one variable must be a radical having at least 4 carbon atoms and where the urea or urethane functionality must be replicated via bridging members, for improvement of the use properties of mineral and synthetic nonaqueous industrial fluids.
