Abstract
It is shown that hydrophobically modified polymer can induce several types of equilibrium phase behavior, depending on the strength of the hydrophobic association. With negligible attraction between polymer and particles, volume restriction flocculation results at moderate polymer concentrations. With low but significant modification, the dispersion is stable against volume restriction flocculation at polymer concentrations where unmodified chains would induce volume restriction flocculation. Finally, strongly modified polymer can induce bridging flocculation. Finally, strongly modified concentrations, but the system restabilizes as the polymer solution becomes concentrated (O(1 wt%)).
