摘要：

Modified Flory's equation of state theory(EOS) was extended to study the phase behavior of ternary blends PS/PMMA/SAN containing a copolymer. EOS parameters(the characteristic parameters) for copolymer SAN were evaluated from those for the constituent monomer segments by using proper combining rules, and binary segmental interaction energy density parameters between homopolymer and copolymer were computed by using simple binary interaction model. The phase behavior of the ternary blend PS/PMMA/SAN was predicted overa wide temperature range and the calculated Spinodal curves agreed satisfactorily with the experimental data.
