We examine whether a small amount of strong polyelectrolyte (dextran
sulfate sodium salt /DSS/) can induce mixing of BSA and dextran in
aqueous water-in-water BSA/dextran emulsion and how intermacromolecular
interactions affect its rheological properties.
Addition of DSS to water-in-water emulsion at pH 5.4 leads to its mixing,
a noticeable increase in viscosity and module (G). Mixing is observed at the
DSS/BSA weight ratio, qBSA 0.07. Increasing the ionic strength in the
resulting single-phase system induces phase separation. Our results show that
