ABSTRACT:
Rheology modifiers useful in water-based and organic solvent-based compositions are derived from the reaction of polyalkylene oxide, polyfunctional material, diisocyanate, water and a monofunctional active hydrogen-containing compound or monoisocyanate. The modifiers are characterized by having a branched structure, urea linkages and terminal hydrophobic groups.
