Flory-Huggins theory for the solubility of heterogeneously-modified polymers

, 2007
Many water soluble polymers are chemically modified versions of insoluble base materials such as cellulose. A Flory-Huggins model is solved to determine the effects of heterogeneity in modification on the solubility of such polymers.
