ICR 7024 IMPROVED USE OF FLOW IMPROVERS Abstract of the Disclosure Friction loss in hydrocarbon fluids flowing through conduits is reduced by adding to said hydrocarbon fluids an effective amount of an ultrahigh-molecular-weight polyolefin having an inherent viscosity of at least 11.0 deciliters per gram, said polymer added to said hydrocarbons in the form of a solution containing less than 10.0 weight percent active material. When added in this form, reduction in friction loss is surprisingly much higher than for similar concentrations of polymer added to the hydrocarbons in a more highly concentrated form.
