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

Experimental investigations of both bulk and surface rheology of solutions of commercially available polymers Aculynac 22 and Aculynac 33 in presence of sodium chloride are performed in a wide range of the polymer and salt concentrations.

Description
Summary:Experimental investigations of both bulk and surface rheology of solutions of commercially available polymers Aculynac 22 and Aculynac 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 100a500 mPa s.
