## Abstract The polystyrene molecule can suffer chain scission by betaβcleavage mechanism in the presence of Lewis acids. This is an undesirable secondary reaction, particularly when the FriedelβCrafts alkylation is applied to immiscible polyolefin/polystyrene (PS) blends compatibilization. It comp

Gel permeation chromatography has been successfully used to determine the compositions of the conjugate phases in the system of polystyrene and poly(methy1 methacrylate) with toluene as solvent. Application of this method to equilibrated samples yields tie lines, binodal curves, and plait points. Po
Cloud points measured [90] (open symbols) for the system CH/ PS-X (the molecular weight of PS in kg/mol is indicated at the curves) plus spinodals (dashed lines), binodals (solid lines) and critical points (full symbols) calculated according to the SLLFT.
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
