A detailed examination thermodynamic theory of polymer blends can be tested in the case a polymers A and B (the degree of polymerization of B is 40, i.e., NB = 20). Assuming the value of Flory Huggins interaction parameters X is 0.1. Please

(e) From your plot, where are the compositions of the non-homogenous mixtures becoming metastable? Show your step to determine how you get the information. [Note that is the Boltzmann constant.]
