ABSTRACT:
Disclosed herein is a stable aqueous dispersant solution containing a high concentration of an EO/PO nonionic block copolymer incapable of liquid phase continuity at ambient temperatures, and a formulation and processing approach providing an effective combination of an anionic dispersant with a water miscible solvent in an aqueous system that allows the feasible production of a dispersant solution containing a high concentration of EO/PO nonionic block copolymer.
