Publication number: 20230375143Abstract: 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.Type: ApplicationFiled: February 13, 2023Publication date: November 23, 2023Inventors: Zhiyi BAO, Stuart N.

Patent number: 9951151Abstract: 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.Type: GrantFiled: January 26, 2011Date of Patent: April 24, 2018Assignee: LiquidPower Specialty Products Inc.Inventors: Zhiyi Bao, Kenneth W.
