With the aid of ~(13)C--NMR spectra of liquid polyoutadiene(PB), catalytically synthe-sized by Co(Nap)_2 -Al(i-Bu)_3 -PhCCl_3, some terminal structures of PB Ⅰ-Ⅵ and twobranch structures ⅩⅥ and ⅩⅦ have been identified, providing valuable informationfor chain initiation mechanism. On the basis of branch structure the number averagemolecular weight of samples was calculated and compared with the result obtained fromVPO measurement.The ~(13)C NMR spectra of PB modified by α-olefine reveal that α-ole-fine only modifies...
