In the early 1940s, Paul Flory and Maurice Huggins , both working independently, developed a theory based upon a simple lattice model that could be used to understand the nonideal nature of polymer solutions . They consider a lattice model where the lattice sites are chosen to be the size of a solvent molecule and where all lattice sites are occupied by one molecule. The mixing entropy and free energy of a polymer solution are evaluated. The appearance of unstable regions and the transition between a homogeneous and a two-phase system are discussed.
