Formation and properties of some polyelectrolyte complexes between strong complementary polyelectrolytes

The particular aspects of the formation and stability, of polysalts obtaine d by the reaction between one polycation of integral type with (N,N-dimethy l-2-hydroxypropylene ammonium chloride) units in the main chain (PCA(5)) an d poly(sodium styrenesulfonate) (NaPSS) as polyanion were, followed in this work. The complex formation in diluted aqueous solutions and the polyelect rolyte complexes (PECs) behaviour ill the presence of NaCl were followed by viscometry, conductometry and W-VIS spectroscopy. Stoichiometric PECs were obtained, independently of the molar ratio between NaPSS and PCA,.
