Abstract: The process begins by obtaining a first batch of monomers selected from a group of acrylates with a molecular weight equal to or less than butyl acrylate and/or methacrylate with a molecular weight equal to or less than butyl methacrylate. A second batch of monomers is then selected from a group of acrylates with a molecular weight greater than butyl acrylate and/or methacrylate with a molecular weight greater than butyl methacrylate. A mixture is then prepared by mixing the first batch of monomers and the second batch of monomers, wherein the second batch of monomers are greater than 50% by weight of the mixture. Finally, the mixture is polymerized to produce a drag reducing polymer. The drag reducing polymer is capable of imparting drag reducing properties in liquid hydrocarbons.

Abstract: A drag reducing composition comprising at least one non-polyalphaolefin polymer having an average particle size in the range of from about 5 to about 800 micrometers. The non-polyalphaolefin polymer can initially be formed via emulsion polymerization. The initial polymer particles can then be at least partially consolidated and then reduced in size and suspended in a carrier fluid. The resulting drag reducing composition 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.

Abstract: A method of producing a polymer latex drag reducer. The method begins by forming an aqueous solution comprising a surfactant, a buffer and water. The method then forms an organic solution comprising a monomer and a co-stabilizer. The aqueous solution and the organic solution are mixed to form an emulsion. The emulsion is then subjecting to a high shear device to produce a miniemulsion, wherein the monomers are broken into small droplets followed by polymerizing the miniemulsion with the addition of an initiator, wherein a nucleation occurs in the small monomer droplets.
