摘要：
Neodymium-based heterocyclic Schiff base complex was prepared and applied for the coordination polymerization of isoprene. This complex polymerized isoprene to afford products featuring high cis-1,4 stereo specificity (ca. 95%) and high molecular weight (ca. 10(5)) in the presence of the tri-isobutyl aluminium (AliBu(3)) as cocatalyst. The microstructure of obtained polyisoprene was investigated by FTIR, (1) H NMR. Two different kinds of active centers in the catalyst system were examined by GPC method. (c) 2008 Wei Lin Sun.
