摘要：

Using general thermodynamic arguments for an incompressible lattice system, we demonstrate that the effective chi must be a complicated function of temperature, composition, polymerization indices, and the coordination number of the lattice, even though the bare chi is merely a parameter. We go beyond the random mixing approximation and present a lattice theory of mixtures which yields an effective chi consistent with experiments.
