More Information
Summary:The present invention relates to a nonaqueous method of dispersing a water soluble polymer, in particular to a method of dispersing and hydrating a water soluble polymer. The method herein comprises forming a nonaqueous slurry of one or more polyethers, one or more water soluble polymer, and hydrophobically modified ethoxylated urethane, provided that the slurry contains less than five percent water. The nonaqueous slurry can be put in contact with water to disperse and hydrate the water soluble polymer.
