Chapter 8 Polyacrylamides – ScienceDirect
High viscosity aqueous solutions can be generated with low concentrations of polyacrylamide polymers, which are injected to improve the economics of conventional water-flooding. In a separate application, hydraulic fracturing benefits from drag reduction resulting from injection of these solutions.
Degradation of polyacrylamide (PAM) in aqueous solution by …
Interaction between linear PAAm and MB results in decrease in PAAm viscosity at high shear rates and increase in storage modulus of mixed solution. Even low amount of MB results in increasing of ultimate compression of PAAm hydrogel, while concentration of MB in semidilute solution regime results in significant increase of hydrogel strength …
