Abstract
It has been convincingly demonstrated, that thermoreversible gelation of atactic polystyrene (a-PS) is the consequence of liquid-liquid phase segregation arrested by vitrification in accordance with the scheme of Arnauts and Berghmans [1], in this cajse for cyclohexanol as solvent. Matrix inversion fran a solvated rubbery to a glassy matrix with increasing polymer concentration has been demonstrated with bicontinuous network structures in the intermediate stages, both by macroscopic constituency and by SEM study of the morphology. The onset of bicontinuous network structures is associated with passing fran the metastable to the spinodal region of the phase diagram.
