摘要：The polymerization of 1-decene catalyzed by rac-Me2Si(1-indenyl)(2)ZrCl2/(AlBu3)-Bu-i/[C6H5NH(CH3)(2)][B(C6F5)(4)] system with hydrogen has been carried out in the paper. The influence of reaction conditions on catalytic activity and polymer properties was investigated. High activity (17.2 x 10(6) g molZr(-1) h(-1)) was observed under the optimized reaction conditions. The introduction of hydrogen enhances the catalytic activity of the metallocene system. The H-1 NMR spectra revealed the polymerization mechanism with the presence of hydrogen. The C-13 NMR spectra of poly(1-decene) indicated that the polymer has a very tactic side chain structure, showing potential application of the system in the commercial production of lubricant base oil.
