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.
