Bulk and surface rheology of Aculyn™ 22 and Aculyn™ 33 polymeric solutions and kinetics of foam drainage

This paper was accepted for publication in the journal Colloids and Surfaces A: Physicochemical and Engineering Aspects and the definitive published version is available at http://dx.doi.org/10.1016/j.colsurfa.2013.05.072Experimental investigations of both bulk and surface rheology of solutions of commercially available polymers AculynTM 22 and AculynTM 33 in presence of sodium chloride are performed in a wide range of the polymer and salt concentrations. It is shown that the bulk viscosity and the surface viscoelastic modulus of solutions of both polymers increases with the increase of polymer concentration and the decrease of the salt concentration. Solutions of both polymers demonstrate very good foamability and form stable foams. Foam drainage is governed mainly by the bulk viscosity when the latter is in the range of 100-500 mPa·s
