    Abstract: Described are methods of dispersing and hydrating a water soluble polymer, comprising 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.
