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 stereospecificity（ca.95%）and high molecular weight （ca.10;）in the presence of the triisobutyl aluminium（AliBu;）as cocatalyst.The microstructure of obtained polyisoprene was investigated by FTIR,;H NMR.Two different kinds of active centers in the catalyst system were examined by GPC method.
