POLYMERIZATION MECHANISM OF DIENES WITH HOMOGENEOUS RARE EARTH CATALYSTS

Received Date: 5 November 1988

The reaction mechanisms of diene polymerization with homogeneous rare earth catalyst are studied by means of the spectra of1H-NMR, one-and two-dimensions 13C-NMR. Based on the data of above NMR spectra, it is proposed that the polymerization reaction proceeds according to the following mechanism: η4-diene (cis-trans-)and η3-allyl (syn-anti-).
