Two n-heptane-precipitated asphaltene samples, characterized by elemental analysis and nuclear magnetic resonance spectrometry, were fractionated according to relative molecular size by gel permeation chromatography (CPC). Both the whole asphaltene samples and their fractions were analysed by pyroly

## 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
