Abstract:
Described are methods of dispersing and hydrating a water soluble polymer, comprising forming a nonaqueous slurry of polypropylene glycol, water soluble polymer, and hydrophobically modified ethoxylated urethane, provided that the slurry contains less than five percent water; and then contacting the nonaqueous slurry with water to disperse and hydrate the water soluble polymer.
