| Abstract: | Pyrolysis products generated in combustion of polymer materials may complicate the interpretation of chromatograms. In this work, a series of combustion experiments were conducted to study the pyrolysis products of typical polymers in fires, and the pyrolysis mechanisms involved were analyzed. Also the combustion experiments of polymers were conducted under the presence of gasoline, by which the impact of pyrolysis products on the gasoline identification was studied. |
