Evidence of modification was provided by metathesis degradation with (E)-4-octene using the catalyst WCl6/Sn(CH3)4. The low-molecular-weight products were identified by combination of gas chromatography (GC) and mass spectrometry (MS). Products characteristic of polybutadiene with cyclooctadienyl substituents at the methylene groups were found. Substitution was partially coupled with double bond shift. The structure of the modified polymer corresponds to polybutadiene crosslinked by dehydrodimerization of methylene groups.
