Abstract
A method of forming a drag reducing polymer formulation. The method begins by forming a drag reducing polymer. A hydrocarbon additive is then incorporated with the drag reducing polymer to form a drag reducing polymer formulation. The drag reducing polymer formulation is then used as a drag reducer in hydrocarbon pipelines.
