An investigation of the pyrolysis products of some polystyrenes prepared by different methods is performed by Mass and IR spectroscopic techniques over the temperature range 30-450-degrees-C. Main pyrolysis product of the polystyrene samples obtained by a free radical initiator and gamma-rays is found to be styrene; whereas, toluene, ethylene and methane are observed as the pyrolysis products of plasma initiated polystyrene. The results demonstrate the dependence of pyrolysis products on polymer structure.
