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 250°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 -320°C, for 1-24 h. The results showed that the presence of water in
The pyrolysis of linear and cross-linked polystyrenes is studied using molecular fluorescence spectroscopy, high-performance liquid chromatography (HPLC) with UV absorption and fluorescence emission detectors, and mass spectrometry. In common with many aromatic systems, polystyrene pyrolysis product
