species, via pyrolysis of alkanes to produce olefins which are subsequently aromatized by a Diels-Alder type reaction to form PAHs, is well known. For example Fairburn et al. examined the flash pyrolysis of n-hexadecane in a microreactor at temperatures

decomposition result from the fact that the macromolecules of BR contain 87–93% mers with a cis 1–4 structure. During the initial stage of pyrolysis butadiene mers react, according to Diels-Alder's mechanism, with alkanes (C 1 –C 3 ) and alkenes (C 2 –C 6
