WebLimitations of Flory-Huggins. Flory himself noted the limitations of this theory. 1 Primarily, this is due to lack of a sufficient mathematical treatment of the individual composition of each polymer, as well as requirement of a strict lattice system. Similarly, FH theory does not account for a change of volume upon mixing, and the chi parameter is assumed to be …
