Salting-out and salting-in of polyelectrolyte solutions: A liquid-state theory study

P Zhang, NM Alsaifi, J Wu, ZG Wang - Macromolecules, 2016 - ACS Publications
We study the phase behavior of polyelectrolyte (PE) solutions with salt using a simple liquid-
state (LS) theory. This LS theory accounts for hard-core excluded volume repulsion by the …
