摘要：The oligomerization of isoprene catalyzed by Cp2TiCl2 and cocatalyst (cocatalyst = iPrMgCl, NaH, MAO(methylaluminoxane), DIBAL(diisobutylaluminum hydride))has been studied. The two dimers, 2,6dimethyl1, trans3,6octatriene and 3,6dimethyl1,3,6octatriene were obtained by distilling under reduced pressure and characterised by GCMS? 1HNMR? 13CNMR and GCIR. The higher oligomer which was extracted by petroleum ether was analyzed by MS and 1HNMR. The mass spectrum shows that the molar weight of the higher oligomer is within 1224, accordingly, the degree of polymerization is ranged from 3 to 18.
