ABSTRACT:
A liquid, pourable rheological additive especially useful for thickening organic and solvent-based compositions which in one aspect comprises an alkoxylated nitrogen-containing compound, polycarboxylic acid, and a functional chain ending unit. The additive, which exists in a pourable, pumpable form at up to a 100% rheologically active composition, exhibits excellent thickening efficiency for systems including inks, epoxies, polyesters, paints, greases and other systems, including ease of dispersibility, without adversely affecting gloss. The additive operates by both an associative and a reaction mechanism to provide rheological viscosity properties to such systems, and is also similarly useful for aqueous systems.
