  • Friction reducing copolymers and method of preparation thereof
    Patent number: 11845858
    Abstract: A friction reducer comprising a copolymer of acrylamide, an anionic monomer, a zwitterionic monomer or a cationic monomer, a physical ligand or a chemical ligand, wherein the acrylamide amounts to at least 50% (w/w) of the total monomer content. The friction reducer is useful in hydraulic fracturing operations and is obtained by controlled radical polymerization at a temperature between 30° C. and 70° C. using iodine as polymerization control agent.
    Type: Grant
    Filed: December 10, 2021
    Date of Patent: December 19, 2023
    Assignee: YPF TECNOLOGIA S.A.

  • METHOD OF PREPARATION OF NEW SUPER-HYDROPHOBIC MEMBRANES AND MEMBRANES OBTAINED BY SAID METHOD
    Publication number: 20210039049
    Abstract: A method for preparing a super-hydrophobic membrane by cleaning a metal mesh by immersion in an organic solvent; subjecting the cleaned metal mesh to a surface modification treatment to increase its hydrophilicity; coating the treated metal mesh with a hydrophobic organic substance; and drying the metal coated mesh for obtaining the super-hydrophobic membrane. The super-hydrophobic membrane obtained thereby.
