ABSTRACT:
The present invention relates to improved thickening compositions, often referred to as Theological additives, used to provide viscosity control, flow, leveling and other rheological properties to clear aqueous systems such as automotive clear-coat paints and coatings. The invention hereof involves the synthesis of a new family of Theological additives by combining, through a reaction process, chemicals used to make specified polyurethane polymer compositions. These novel copolymers provides the good flow and leveling and gloss retention that polyurethane associative thickeners impart to water-based systems, without the loss of clarity that such polymers have caused in the past. Levels of the rheological thickening composition, varying between about 0.01% and about 10%, based on the total weight of the system to be thickened, have been found to be useful to create novel clear aqueous systems containing such thickening compositions.
