The free energy of mixing (per mole of lattice sites) of a polymer (B) solution in A (according to the Flory- Huggins model) is RT In +- - In OB + XOAPB B where R is the gas constant and the interaction parameter is x = x/T, where x₁ = 300K. Plot the critical parameters (₁.B. XeT) for the solution as a function of the degree of polymerization SB.
