Zusammenfassung:A polymer dispersion includes a water-soluble copolymer prepared by controlled radical polymerization; a water soluble salt; a polyol; a salt selected from the group consisting of sodium citrate, sodium phosphate, sodium nitrate, and combinations thereof; and water. Methods for using the polymer dispersion for oilfield friction reduction occur under a variety of adverse conditions including low temperatures, salt, scale, and iron.
