Abstract
A drag reducing composition comprising particles of at least two different drag reducing polymers. The different drag reducing polymers can be formed by different processes, such as bulk polymerization or emulsion polymerization, and the particles of the different drag reducing polymers can have different mean particle sizes. The drag reducing compositions can be added to a hydrocarbon-containing fluid to decrease the pressure drop associated with the turbulent flow of the hydrocarbon-containing fluid through a conduit.
