ABSTRACT:
The thermal aging stability of liquid suspensions of hydrophilic, water-soluble polymers in an organic liquid is improved by adding to the suspension a liquid fatty acid. Superior liquid polymer compositions having improved resistance to settling (syneresis), thermal aging characteristics, viscosity, and dispersibility in aqueous liquids comprise from about 40% to about 55% of an organic liquid, from about 35% to about 55% of a hydrophilic, water-soluble polymer, from about 2.0% to about 4.5% of an organophilic clay suspending agent, from about 0% to about 2.0% of a dispersant for the organophilic clay, from about 0.5% to about 2.5% of a non-ionic surfactant, and from about 1.25% to about 5.0% of a liquid fatty acid.
