英文摘要A novel late transitional metal catalyst-(2-Me-3-ClPh)(2)PBIMe2FeCl2-has been synthesized having a high oligomerization activity up to 1.0 x 10(7)g oligomer/( mol Fe (.) It). Using this oligomenization catalyst and metallocene catalyst-rac-C2H4 (Ind)(2)ZrCl2-as a dual functional catalyst system, MAO as the only cocatalyst, Linear Low Density Polyethylene (LLDPE) has been prepared by in situ copolymerization of ethylene having a high activity [> 10(6)g PE/( mol cat (.) h)]. C-13-NMR shows that the LLDPE is obtained. In addition, the presence of unreacted alpha-olefin was not detected since there is no evident resonance signal at 29.29 and 29.42, which proves that this dual functional catalyst system has a good match during in situ copolymerization. With increasing the Fe/Zr ratio, the densities of polymers and the melting points of polymers obtained from DSC are in a descending trend. Meanwhile, the similar phenomenon is also found when the reaction temperature decreases.
