Isothermal miscibility maps for blends of styrene–acrylonitrile (SAN) copolymers with methyl methacrylate (MMA) copolymers containing ethyl acrylate (EA) and n-butyl acrylate (nBA) have been determined. The miscibility region for MMA-nBA copolymers is larger than that for MMA-EA copolymers. Binary interaction energies for monomer unit pairs were calculated from critical molecular weight experiments and data from the miscibility maps using with the Flory–Huggins theory combined with the binary interaction model. Spinodal temperatures predicted from the lattice-fluid theory of Sanchez and Lacombe, using these experimental interaction energies, are similar to the experimental phase separation temperatures.
