The mechanism of the thermal degradation of polystyrene was studied by pyrolysis-gas chromatography and pyrolysis-field ionization mass spectrometry, using a block copolymer of ordinary and perdeuterated styrene [poly(styrene-b-styrene-ds) ]. The main degradation products were monomers, dimers and t
## Abstract A series of substituted acetylenes has been polymerized with WOCl~4~/Ph~4~Sn metathesis catalyst and [Rh(cod)OMe]~2~ insertion catalyst, and the thermal degradation of the polyacetylenes prepared has been studied using pyrolysis capillary gas chromatography (PyβGC) with flame ionization
