This work investigates the elongational flow of aqueous solutions of mixtures of a high-molecular-weight poly(ethylene oxide) (PEO) and sodium dodecyl sulfate (SDS). The formation of micellar aggregates of SDS along the PEO chain results in an increase in the strength of the extension thickening of

In this work, the porous media flow of polymer solutions of poly(ethylene oxide) (PEO), hydrolyzed polyacrylamide (HPAA), and their blends is investigated. Aqueous solutions of PEO exhibit critical extension thickening when flowing through porous media. HPAA solutions also exhibit critical extension
The effect of the presence of n-alkanols on the extensional rheology of solutions containing polymer/surfactant complexes has been investigated experimentally in an opposed-jets device. Aqueous solutions of high-molecular-weight poly(ethylene oxide) (PEO) and sodium dodecyl sulfate (SDS) exhibit an
## Abstract **Summary:** The effects of PEO concentration, addition of PEG of various molecular weights (1 000–35 000 g · mol^−1^), inorganic salt of various types (i.e., NaCl, LiCl, KCl, MgCl~2~, and CaCl~2~), or SDS, and the solvent system (i.e., mixed solvents of distilled water and methanol, et
