image text in transcribed How would you mathematically find the spinodal points in the above problem?

1. The Flory-Huggins parameter between polystyrene (PS) and poly(methyl methacrylate) (PMMA) is given by: =0.0129+T1.96 (i) For a blend of PS/PMMA ( NA=NB=1000) containing a PS volume fraction of =0.20, will the blend phase separate by spinodal decomposition or nucleation and growth?
