摘要:
The present invention relates to multi-arm star macromolecules which are used as thickening agents or rheology modifiers, including use in hydraulic fracturing fluid compositions. In one aspect of the invention, a star macromolecule is capable of thickening via a dual mechanism comprising (1) self-assembly of the hydrophobic polymerized segments of the star macromolecules via hydrophobic interactions or associations, and (2) association, reaction, or combination of the hydroxyl-containing polymerized segments of one or more of the star macromolecules.
摘要:
The present invention relates to synthetic polymers having high molecular weight and low polydispersities, and methods of synthesis thereof. One embodiment of the present invention provides a method of polymerizing that includes dissolving acrylate monomers in a fluid media having an olefin- containing polyalcohol amide surfactant; and initiating a polymerization reaction of the acrylate monomers with a polymerization initiator to produce a polymer having a molecular weight of at least about 500,000 and a polydispersity index of about 1.25 or less.
