摘要：
The present invention is a process for preparing an aqueous solution of a hydrophobically modified alkylene oxide poly(urethane-urea-allophanate) thickener by contacting isocyanate reactive groups with a stoichiometric excess of a diisocyanate, followed by reaction with water. The thickener surprisingly shows a maintenance or improvement in hiding in paint formulations while maintaining other critical rheological properties.
