Structure formation in solutions of atactic polystyrene in <i>trans</i>‐decalin

Abstract

Abstract The temperature‐concentration diagram for the system atactic polystyrene/ trans‐ decalin System. name: trans ‐decahydronaphthalene. was studied by optical observations and calorimetric investigations. A liquid‐liquid demixing interferes with the glass transition of the polymer‐solvent system. It results in the solidification of the solution. The binodal, the spinodal and the position of the critical point were investigated for a sample with narrow molecular weight distribution. The formation of different morphologies, based on different cooling processes, is illustrated.
