Goldstein extended this theory with a two-term partition function for H-bond interactions, while LCST behavior cannot be accounted for by this theory and require adding "holes". A variation of this theory by Krigbaum adds a term for volume elements, and considering the critical temperature for an infinitely-long molecule in this theory gives rise to the theta point. This theory is derived by considering a lattice in which each space can only be occupied by one monomer, then calculating the combinatorial entropy assuming ideal mixing. Usually expressed in terms of the Gibbs free energy expansion plus an interaction term chi, for 10 points, name this theory used to model the mixing of polymer solutions, named for two guys.
