Abstract
The present invention relates to a drag reducing agent, composition, compound, product, process and method of use for use in petroleum pipelines and the like. A preferred embodiment of the present invention provides a cryogenically-ground polyalphaolefin polymer at 15-25 wt. % of the commercial product formulation. The bulking agents comprise ethylene bis-stearamide alone or in combination with other polyethylene and/or polypropylene polymers at 2.0-5.0 wt. % of the commercial product formulation. In addition, diisobutyl ketone 20-60 wt. % of the commercial product formulation and propylene carbonate 2.8-8.4 wt. % of the commercial product formulation are used.
