Polystyrene (PS) samples carrying terminal or in-chain nitroxide spin labels have been blended with poly(vinyl methyl ether) (PVME) in varying proportions and their electron spin resonance (ESR) spectra recorded over a range of temperatures. The spectra are mainly of the slow-motion type but reΓect

## Abstract **Summary:** Experimental observations of the dynamics of phase behavior for blends of reactive constituents, i.e. diglycidyl ether of bisphenol A (DGEBA), curing agent methylene dianiline (MDA), and a reactive liquid rubber (R45EPI), have been theoretically modeled by coupling system t
The phase diagram and cloud point surface for the ternary system polystyrene/polybutadiene/tetralin were determined a t 29", 87", and 143Β°C. Polystyrenes and polybutadienes of narrow molecular weight distribution were used to study the effect of molecular weight on the cloud point concentration. The
