Some Limitations of the Flory - Some Limitations of the Flory - Huggins Theory Huggins Theory
1.Based on a lattice model that uses various approximations in the “counting” process
2. Ignores "free volume” and only accounts for combinatorial entropy
3. Assumes random mixing of chains in calculating the entropy and segments in calculating the enthalpy
4. Only applies to non - polar molecules
5. Does not Apply to Dilute Solutions
