The dynamics and structure were investigated for polyelectrolyte-rich liquids across the high-salt region of the complex coacervation phase diagram of high molecular weight poly(sodium 4-styrenesulfonate), PSS, and poly(diallyldimethylammonium chloride), PDADMAC. The total concentration of polyelectrolytes was increased at different added KBr concentrations ([KBr]) to obtain liquid complex coacervates (CC) and single-phase, high-salt polyelectrolyte solutions. The dynamic response of these entangled polymer liquids was found to be self-similar at each [KBr], allowing a time-polyelectrolyte superposition using only a polyelectrolyte concentration-dependent horizontal shift factor. This self-similarity was further found among all the samples at different [KBr], allowing the construction of a universal master curve unifying the dynamics of all the samples by applying a second, salt-dependent horizontal shift factor. The complex coacervate dynamics were found to have a very strong dependence on the experimentally determined PEs concentration, while salty solutions of non-interacting PEs behaved as polymers in good solvent. The extreme scaling in the case of the CC defies the predictions for entangled associating polymers, probably due the very high polymer concentration and the large number of stickers per chain. Despite the absence of effective stickers in the salty solutions of fully doped polyelectrolytes, they can mimic the viscoelastic response of the CCs up to the solubility limit of the PEs. We called these materials quasi-complex coacervates (quasi-CCs) to distinguish them from both CC and single-polyelectrolyte solutions. Small angle X-ray scattering (SAXS) revealed that PSS/PDADMAC CC, their quasi-CCs, and a PSS solution at the same total polymer and salt concentration have different nanostructures. Unifying the dynamics of viscoelastic liquids across the high-salt region of the phase diagram, time-polyelectrolyte-salt superposition may be regarded as a route to predict the composition and properties of these polyelectrolytes-rich materials.
