| Abstract: | A new type of supported catalytic system (NdCl_3·TBP/MgCl_2-Al (i--Bu)_3 was prepared with MgCl_2 as the carrier. Some laws of the polymerization of isoprene with the supported catalytic system were researched. The results showed:This supported catalytic system was advantageous to polymerization of isoprene and the supported Nd amount of 3% was advisable. The molecular weight of polyisoprene was great,the molecular weight distribution was narrow and the curve of GPC was of single peak. And investigated by the combination of IR and ~(13)C-NMR, the chain structure of the synthesized PIp was characterised by the content of about 95% cis-1,4-chain unit of polyisoprene. |
