We extended and simplified the modified double‐lattice model to binary polymer blend systems. The model has two model parameters, C β and C γ . Those are not adjustable parameters but universal functions. In comparison with Ryu et al. 's simulation data for symmetric polymer blend with various chain lengths ( r 1 = r 2 = 8, 20, 50, 100), C γ is determined. Our results show that C β is negligible for symmetric polymer blend systems. The proposed model describes very well phase behaviors of weakly interacting polymer blend systems.
