mixing/demixing of biopolymer mixtures in the presence of strong
biopolymer solutions to biopolymer emulsions)
intermacromolecular interactions caused by the presence of a complexing agent
in two phase biopolymer mixture can affect its phase equilibrium and
morphology. In this communication, the attempt was performed to induce demixing
in semidilute and concentrated biopolymer systems in the presence of sodium
salt of dextran sulfate (DSS), and to characterize phase equilibrium,
intermacromolecular interactions, and structure of such systems by rheo-small angle light scattering (SALS), optical
microscopy (OM), phase analysis, dynamic light scattering (DLS), fast protein
liquid chromatography (FPLC), ESEM, and rheology.
