Abstract
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.
Claims20
A method comprising:
- dissolving acrylate monomers in a fluid media comprising an olefin-containing polyalcohol amide surfactant;
- and
- reacting 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.
A method comprising:
- providing a treatment fluid comprising:
- a base fluid;
- and
- a polyacrylate polymer having a molecular weight of at least 500,000 and a polydispersity index of about 1.25 or less;
- and
- placing the treatment fluid in a subterranean formation.
A method comprising:
- providing a fracturing fluid comprising:
- a base fluid;
- a polyacrylate polymer having a molecular weight of at least 500,000 and a polydispersity index of about 1.25 or less;
- and
- introducing the fracturing fluid in a subterranean formation at a rate sufficient to create or enhance at least one fracture in the subterranean formation.
