Oligomers of polystyrene (PS) obtained from initial degradation studies of an anionic polymerized styrene have been degraded in uucuo using the molecular still method at temperatures between 150 and 250Β°C. The volatile decomposition products were separated and characterized by gel permeation chromat
Thermal degradation of polystyrene has been studied in the presence of water under subcritical conditions (hydrous pyrolysis). The experiments were performed in closed systems under inert atmosphere, in the temperature range of 300 -320Β°C, for 1-24 h. The results showed that the presence of water in
