Abstract: | The polyelectrolyte – surfactant complexes formation has been studied. The critical micelle concentration for every polyelectrolyte and surfactant which had been used has been measured on this purpose The phase behaviour of mixtures of a cationic polyelectrolyte (Praestol 644) and an anionic surfactant (sodium lauryl sulphate – SLS) has been studied. Three phase regions were identified for a given polyelectrolyte concentration, with increasing surfactant concentration. The rheological consequences of interactions of polyelectrolytes with surfactants of the opposite charge are experimentally studied. The results reveal that the Praestol 644 solution has the Bingham pseudoplastic, reopectic and viscoelastic and the complex solutions lose the viscoelastic and rheopectic rheological properties. |
