| Abstract: | Thermal degradation of four polysulphides, poly(methylenesulphide), poly(methylenedisulphide), poly(methylenetetrasulphide), and poly (styrenesulphide)-co-poly(methylenesulphide) have been investigated by pyrolysis gas chromatography/ mass spectrometry technique (Py-GC/MS). The pyrolysis products detected by Py-GC/MS indicate that the thermal decomposition of these polymers yields cyclic sulphides by an intramolecular exchange process. The linear products with thiol end groups also form along with the cyclic products through a β-CH hydrogen transfer reaction. |
