Abstract
We study mixtures of polymer solutions with particles whose diameter is much smaller than the radius of gyration of the polymer. They are found to demix when the polymer is semidilute and its correlation length is approximately equal to the particle’s diameter. Protein purification using polymer solutions is shown not to be possible without attractive polymer-protein interactions.
