摘要：

The degradation of unsaturated polymers by olefin metathesis has already been applied to the investigation of crosslink structures. In the present paper, crosslinks in poly(butadiene-alt-propene), obtained by partial bromination with N-bromosuccinimide and reaction with 1,4-bis(bromomagnesium)butane, were investigated by this method. Metathesis degradation was carried out 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).
