Oligomers of polystyrene (PS) obtained from initial degradation studies of an anionic polymerized styrene have been degraded in vacuo using the molecular still method at temperatures between 150 and 250°C. The volatile decomposition products were separated and characterized by gel permeation chromatography, gas liquid chromatography, infrared spectroscopy, mass spectroscopy, and nuclear magnetic resonance. The products of pyrolysis showed that at 150°C the major component formed was the dimer, whereas at 250°C, the trimer was the major component. © 1993 John Wiley & Sons, Inc.
